Question

Friend :befriend :: act :

Answer 1

As friend is to befriend , act is to react

Answer 2

Answer :

Friend : befriend :: act : react

This question is based on analogy.

Cambridge English Dictionary defines 'analogy' as 'a comparison of the features or qualities of two different things to show their similarities.'

Just like the word 'befriend' is formed by adding the prefix 'be-' to the root word 'friend,' the word 'react' is formed by adding the prefix 're-' to the root word 'act.'
