Select the most appropriate option to fill in the blank.

We decide to _______ as we were missing him a lot.

pay him a visit 

The most appropriate option to fill in the blank is pay him a visit.

The phrase "pay someone a visit" means to go to see them, especially as a social call. It is the most appropriate option in this context because it conveys the idea that the speaker and their friends decided to go to see the person they were missing, as a social gesture.

The other options are incorrect.

• "Give a visit" is not a grammatically correct phrase.
• "Take a visit" means to go to a place for a specific purpose. It does not make sense to say that the speaker and their friends took a visit to the person they were missing.
• "Bring in a visit" is not a grammatically correct phrase.
