In Cisco's Application Centric Infrastructure (ACI), a bridge domain is a Layer 2 forwarding construct that represents a logical segment or broadcast domain.

In traditional networking, a broadcast domain is a logical division of a network in which all devices can communicate with each other without the need for a router. In ACI, a bridge domain is used to group endpoints (such as virtual machines, physical servers, or network devices) together so that they can communicate with each other as if they were on the same physical network.

A bridge domain can span multiple leaf switches within an ACI fabric, and can be associated with multiple subnets. This allows for more efficient use of IP address space, as well as easier management and troubleshooting of network traffic flows.

In ACI, a bridge domain can be associated with a tenant, which represents a logical unit of multi-tenancy within the fabric. A tenant can contain multiple bridge domains, as well as other constructs such as application profiles, endpoint groups, and contracts.

So, the correct answer to the question is B. Layer 2 forwarding construct.
