A Correct answer
Explanation

The phrase 'one and one' is a mathematical expression representing a single calculation that equals two. As a singular concept, it takes the singular verb 'equals'. 'Equal' is the plural form, 'equally' is an adverb, and 'equalent' is a misspelling of 'equivalent'. This follows the rule that mathematical expressions treated as single units use singular verbs.
