D) 186.55.12.0/22

A

B) 186.55.8.0/21

Solution:
186.55.8.0: 10111010.00110111.0000 1000 .00000000
186.55.10.0: 10111010.00110111.0000 1010 .00000000
186.55.12.0: 10111010.00110111.0000 1100 .00000000
186.55.14.0: 10111010.00110111.0000 1110 .00000000

These are the bits that are common across all networks:
