"Reinforcement" is a noun with suffixes and prefixes in its structure.

The root of the word is option a) "force" which means strength or energy.

Options b) and d) are prefixes since they are places before the root of the word

Option c) "ment" is a suffix since it is placed after the root of the word.

The meaning of the word "reinforcement" with its prefixes and suffixes is "the act of making something stronger."

The correct answer is A.

A root word has no prefix or suffix and it is the most basic part of a word. It is what is left of a word after removing all the affixes (the prefixes and suffixes).

Reinforcement - the root word is force.

Re and in are prefixes and have to be removed. Ment is a suffix and is to be removed as well. Only force is left which is the root word.
