Show answer & explanation
Correct answer: B
Explanation
The original sentence uses a double superlative ('most toughest'), which is grammatically incorrect in English. The adjective 'tough' is a one-syllable word, so its superlative form is created by adding the suffix '-est' (toughest), not by using the word 'most'.
