Answer: B) removal.
Explanation: a suffix is a morpheme added at the end of a word to form a derivative. The -ion suffix is a suffix that denotates action or condition. It is used in English to form nouns from adjectives, verbs, and past participles. So the word abolition is a noun that means officially ending or stopping something, from the given options, the only one that is also a noun (and that means the same) is the corresponding to option B: removal.
