Select the most appropriate option to substitute the underlined word in the given sentence.
The city’s infrastructure needs to be updated to keep up with the actual population of New Delhi, which continues to expand rapidly.

The correct answer is '4' current.

Key Points

• The context of the sentence refers to the population of New Delhi that is expanding rapidly in the present time.
• The word "current" is the most appropriate to describe the population that is being referred to at this moment.
• The other options do not fit well in the context of the sentence. "Perpetual" and "ongoing" imply continuity but not necessarily the present time, and "declining" is the opposite of expanding.

Correct sentence: The city’s infrastructure needs to be updated to keep up with the current population of New Delhi, which continues to expand rapidly.
