The correct answer is: B. Guarantee

The word "guarantee" is a noun that means a promise or assurance that something will happen or be done. It is derived from the Latin word "guarantere," which means "to promise." The word "guarantee" is spelled with two "r"s and one "e."

The other options are incorrect because they are not spelled correctly. The word "gaurantee" is missing an "r." The word "garuntee" is missing an "e." The word "Guaruntee" has an extra "u."

It is important to spell words correctly in order to be understood clearly. When you spell words incorrectly, it can make it difficult for people to understand what you are trying to say. It can also make you look unprofessional.
