Choose the correct sentence: ‘What worries me ___ his health.’

Explanation

When the pronoun ‘what’ functions as the subject of a sentence and refers to a single idea or complement, such as ‘his health,’ it takes a singular verb, giving ‘What worries me is his health.’ The verb agrees with the singular sense of the underlying idea being expressed, rather than any plural-sounding words that might otherwise appear nearby.
