Show answer & explanation
Correct answer: C
To determine if computers can communicate directly, we analyze their network segments using the subnet mask 255.255.255.192 (/26). This mask creates subnets with a block size of 64 addresses. The subnet ranges are: 0-63, 64-127, and 128-191. Computer A (10.0.0.126) falls in the 10.0.0.64 subnet, while Computer B (10.0.0.131) falls in the 10.0.0.128 subnet. Since they are on different subnets, a router is required to forward traffic between them.
