Fill in the blank with the suitable Adverb from the given alternatives.

__________ does he visit his hometown as his parents are no more.

Seldom

The correct answer is Option (4) - Seldom

Seldom does he visit his hometown as his parents are no more.

• The adverb "seldom" means "not often" or "rarely," which fits the context of the sentence, indicating that he does not frequently visit his hometown.
• The other options do not convey the intended meaning appropriately:
  • "Ever" implies at any time but does not fit the context.
  • "Quickly" relates to speed, which is irrelevant here.
  • "No sooner" indicates a sequence of events, which is also not appropriate for this sentence structure.
