Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. was.
The sentence is referring to a time in the past when the COVID-19 pandemic had an impact on festivities. The word "after" signals that the pandemic's effect is no longer present, placing the focus on something that was happening in the past.
The main clause refers to the present (the upcoming celebration of Diwali), but the subordinate clause describes a situation in the past. Hence, "was looming" appropriately describes the now-ended situation of the pandemic affecting festivities.
