He did his job with scrupulous care.

The correct answer is: A. exact

The word “scrupulous” means “very careful and thorough, especially in avoiding potential problems or errors.” In this context, it is clear that the man did his job with great care and attention to detail.

The other options are not as accurate. “Marvellous” means “extremely impressive or wonderful.” While the man’s work may have been impressive, the word “marvellous” is not the best choice to describe it. “Great” is a vague word that could mean many things. In this context, it is

not clear what the speaker means by “great.” “Attentive” means “paying close attention to someone or something.” While the man may have been attentive to his work, the word “attentive” does not capture the full meaning of the sentence.

In conclusion, the correct answer is: A. exact.
