A. B. C. D.Answer - A.
The best choice is to use Enhanced Networking.
The AWS Documentation mentions the following on Enhanced Networking.
Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types.
SR-IOV is a method of device virtualization that provides higher I/O performance and lower CPU utilization when compared to traditional virtualized network interfaces.
Enhanced networking provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies.
There is no additional charge for using enhanced networking.
Options B, C and D are used for multiple instances ideally.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.htmlTo achieve higher bandwidth for voice-related traffic on an EC2 instance, the following options can be considered:
A. Enable Enhanced networking on the instance: Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types. This option can help to improve the network performance of the instance and achieve higher bandwidth. However, it is important to note that not all instance types support enhanced networking, and it may require additional configuration on the instance to enable it.
B. Use a Network load balancer in front of the EC2 instance: A network load balancer is a layer 4 load balancer that can distribute incoming traffic across multiple EC2 instances. By using a network load balancer, traffic can be balanced across multiple instances, allowing for higher bandwidth and improved availability. However, it is important to note that a network load balancer may not be necessary if there is only a single EC2 instance handling the traffic.
C. Use a placement group for the EC2 instance: A placement group is a logical grouping of instances within a single Availability Zone. By placing instances in a placement group, network performance can be improved by reducing the network latency and increasing the network throughput between instances. However, it is important to note that placement groups are limited to certain instance types, and they cannot span multiple Availability Zones.
D. Use an Application load balancer in front of the EC2 instance: An application load balancer is a layer 7 load balancer that can distribute incoming traffic across multiple EC2 instances based on application-level information, such as HTTP headers or URLs. By using an application load balancer, traffic can be balanced across multiple instances, allowing for higher bandwidth and improved availability. However, it is important to note that an application load balancer may not be necessary if there is only a single EC2 instance handling the traffic.
In summary, to achieve higher bandwidth for voice-related traffic on an EC2 instance, enabling Enhanced networking on the instance, using a Network load balancer or an Application load balancer in front of the EC2 instance can be considered. Using a placement group may also help to improve network performance, but it is limited to certain instance types and cannot span multiple Availability Zones.
