What is the best course of action if the company wants to have 40 hosts in each of the three subnets?()

A.Convert all the routers to EIGRP and use 198.133.219.32/27, 198.133.219.64/27, and 198.133.219.92/27 as the new subnetworks.

C.Convert all the routers to EIGRP and use 198.133.219.64/26, 198.133.219.128/26, and 133.219.192/26 as the new subnetworks.
D.Convert all the routers to RIP version 2 and use 198.133.219.64/26, 198.133.219.128/26, and 133.219.192/26 as the new subnetworks.
E.Convert all the routers to OSPF and use 198.133.219.16/28, 198.133.219.32/28, and 198.133.219.48/28 as the new subnetworks.
F.Convert all the routers to static routes and use 198.133.219.16/28, 198.133.219.32/28, and
