which may or may not contain an error. Choose the one that is grammatically correct and meaningful. If all the sentences are correct, mark 'All are correct' as your answer.Solution
Sentence A is grammatically correct and meaningful. In sentence B, 'easily'(adverb) should be used in place of 'easy'(adj.), as 'more easily' is the right adverbial phrase.
