c. defensive listener
d. selective listener

b) Insulated listener

Explanation:

The term insulated listeners refers to people who actively avoid or ignore certain topics. This means that when such topic arises in the conversation, they turn off and don't listen to it.

In this example, Spencer friends have told him that they've seen his girlfriend on dates with someone else. However, Spencer never seems to hear what they are saying.

This is a sensitive topic that Spencer prefers to avoid, so when his friends tell him about it, he "turns off" and he doesn't seem to hear what they are saying.

Thus, Spencer is likely an Insulated listener.

Note:

a) Pseudo listeners refer to listeners who seem like they are paying attention to you but they actually aren't.

c) Defensive listeners take every comment as an offence to themselves.

d) Selective listeners will only listen to what it's of interest to them and will ignore the rest of the message.
