Correct option is A
The correct substitution of the highlighted words is (a)
hearings are limited.
Explanation:
The subject "hearings" is
plural, and the verb "is limit" is incorrect due to subject-verb disagreement and tense misuse. The correct passive structure here should be
"are limited" to match the plural subject and present tense context ("These days").
Grammatical rule used:
In passive voice:
be verb (is/are/was/were) + past participle (V3)
→ "hearings" (plural subject) + "are" (present plural auxiliary) + "limited" (V3)
Example: These facilities
are restricted to staff members only.
Information Booster: Always check for
subject-verb agreement and passive structure. In present passive voice with plural subject, use “are + V3.”
