The correct answer is B. tracert (short for "traceroute").
Tracert is a command-line utility that is used to track the path that a packet takes from one device to another on a network. It works by sending packets to the destination device with a gradually increasing time-to-live (TTL) value. Each time a packet is sent, the router that receives it decrements the TTL by one. When the TTL reaches zero, the router sends an ICMP time exceeded message back to the source device. The source device then knows that the packet has reached that router and can use this information to map the path to the destination device.
Tracert displays a list of all the routers that a packet passes through, along with the time it takes for each hop. It also displays the IP address of each router and its DNS name if available. This information can be useful for troubleshooting network connectivity issues or optimizing network performance.
The other options listed are also network diagnostic commands:
Ping (A) is a utility that sends an ICMP echo request to a device and waits for an ICMP echo reply. It is used to test whether a device is reachable on the network and to measure the round-trip time (RTT) for packets to travel between two devices.
Netstat (C) is a utility that displays network statistics and information about active network connections, listening ports, and routing tables on a device. It can be used to troubleshoot network connectivity issues and to monitor network performance.
Route (D) is a command-line utility that displays and manipulates the IP routing table on a device. It is used to view and modify the network routing information used by the device to determine how packets are forwarded to their destinations.
