I think this is wrong, it should be /26 , because 2^6= 64 subnets
32bits-6bits= /26

My bad, it is correct! Answer D

To clarify the previous comment, D is correct because 2^6=64 but you add those 6 bits to the network mask, hence /24+6=/30. Subtracting from 32 would give your host count. So this network would have 2 bits remaining for hosts (2^2-2=2 hosts)
2^x=subnets (x=network bits added to subnet)
2^x-2=hosts (x=host bits borrowed from subnet / minus 2 for network and broadcast address)

we have to select /30
why?
because from this 11111111.1111111.1111111.11111100 we took the last octec
we check 111111 2 x6=64 subnet and
the 00 means the number of host 2×2-2=2 host.
