Although the subnet mask in the questions is listed incorrectly; it should be 255.255.255.240. The IP of the subnet is also listed incorrectly; it should be
10.0.0.0
But since the CIDR is /28 that gives us a block size of 16
first network .0 / next network is .16 / third network is .32 etc. etc.
So the correct answer is still D: Change the IP address of the computer to 10.0.0.12
because it’s still within the subnet of the GW (gateway)ip of 10.0.0.1.
