Despite living in the same neighbourhood, we only did not greet each other.

Correct option is A

The correct substitution of the highlighted words is (a) still.
Explanation: The sentence presents a contrast between living in proximity and not greeting one another. "Still" is the appropriate adverb to show that something unexpected continues despite a condition. The use of “only” is incorrect and disrupts the meaning.
Correct sentence: Despite living in the same neighbourhood, we still did not greet each other.
Grammatical rule used:
• Use “still” to indicate something continues or remains the same, even in surprising conditions.
• “Only” should be used for emphasis or restriction and needs proper placement.
Example: She still refused to talk to me, even after I apologized.
Information Booster:
Adverbs like still, yet, and even are used for contrast and emphasis but must fit contextually and syntactically within the sentence.
