Choose the correct form of tense for the given sentence:
We ______ our dinner when you called.

Correct option is D

The correct tense for the given sentence is were having.
The sentence refers to an action that was in progress when another action (the call) happened. This requires the past continuous tense.
Grammatical rule involved: The past continuous tense is used to describe an action that was ongoing at a particular time in the past. The structure is was/were + verb-ing.
Meanings of the other given options:
· (a) had: लिया था – Past simple, indicates a completed action, but here the action was ongoing.
· (b) have: लेना – Present tense, incorrect because the sentence refers to the past.
· (c) was having: उठा रहा था – Singular form, but the subject "we" is plural, so "were" is correct.
