(Because the flight was cancelled), some passengers had to spend the night at the airport.

Correct option is C

The sentence "Because the flight was cancelled, some passengers had to spend the night at the airport." is already correct.
· "The flight" is singular, so "was" is the correct verb form.
· "Cancelled" is the correct past participle for passive voice.
Grammatical rule used:
In passive voice, the structure is: Subject + was/were + past participle.
Explanation in Hindi:
Passive voice में, "was/were" के बाद हमेशा verb का past participle (V3) आता है। "The flight was cancelled" सही है क्योंकि "flight" एकवचन (singular) है।
Meanings of other options:
· Because the flight were cancelled – Incorrect, "flight" is singular, so "were" is wrong.
· Because the flight was cancelling – Incorrect, "was cancelling" is incorrect for passive voice.
· Because the flights was cancelling – Incorrect, "flights" is plural, so "was" is wrong.
