E is the right answer.
IP belongs to Class B Default Subnet Mask is 255.255.0.0.
Total Subnet required =25+30 =55 2^6=64,
Mask is 1111 1111.1111 1111.1111 1100.0000 0000,
255.255.128+64+32+16+8+4.0.
255.255.252.0.

IP belongs to class B so 255.255.0.0 mask and for that 16 bits.
Remaining bits are 16 out of 16, and now we want 600 host per subnet.
Total subnets = 25+30 = 55, 55<2^6(2^6 = 64 subnet).
So, mask becomes 1111 1111.1111 1111.1111 1100.0000 0000 for subnet.
134.57.252.0.
