Select the most appropriate option to substitute the underlined part of the following sentence.
Mathew decided to complete the marathon to prove that he is still fit as a fiddle in his eighties.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. a fit and energetic person.
"Fit as a fiddle" means being in excellent health and energetic.
The phrase "a fit and energetic person" accurately captures this meaning.
The other options—"an owner of a fit horse," "a man of great qualities," and "proud and unreliable"—do not convey the same sense of physical fitness and vitality.
