Escape is spelled correctly in the excerpt. Escape does not have an x. This means option A is wrong and B is correct. C is also wrong because of the spelling of escape and also because it uses the wrong there. In the sentence, their is a possessive adjective. It shows that enemies "belong" to the monkeys since they are the enemies of the monkeys. There means a place, as in over there. They're is a contraction meaning they are. Option D is wrong because of the spelling of escape and the apostrophe in enemie's. An apostrophe is used for contractions or to show ownership. The enemies do not own anything and it is not part of a contraction.
Escape from their enemies by jumping away is the correct answer because although many people mispronounce the word, there is no x in escape. "Their" is correct because it is a possessive pronoun that tells whose enemies. "Enemies" is a plural noun and does not need an apostrophe.
