Answer: Option B

 

Explanation: 

In the given classless IP address as 167.199.170.82/27; the first 27-bits represent the network portion and the remaining 5-bits represent the host portion.

Since, there are 5-bits available for the host portion. So, the total available addresses in the network are $2^5$ or 32 addresses.
