A sentence has been given with a blank to be filled with an appropriate option.
Snow ________ lightly as everyone was leaving church.

Correct option is C

The correct option to fill in the blank is (c) was falling.
Explanation: The sentence describes a past continuous action happening while another past action (“was leaving”) took place.
(Hindi: जब लोग चर्च से निकल रहे थे, तब बर्फ धीरे-धीरे गिर रही थी।)
Example: The rain was falling steadily as we walked home.
Why other options are incorrect:
· (a) is falling – present tense (वर्तमान काल)
· (b) fallen – past participle; used with “has/have/had”
· (d) falling – needs auxiliary verb like “was” to complete tense
Grammatical rule used:
· Past Continuous: was/were + verb-ing to show an action in progress in the past.
