Correct option is A
The sentence "They serve stuffed garlic bread and molten chocolate in the birthday party of their son, Parth, last week" requires a verb in the past tense to accurately reflect that the actions took place in the past.
· The original verb "serve" is in the present tense, which is inconsistent with the temporal context provided by "last week."
· The corrected version, "They served stuffed garlic bread and molten chocolate in the birthday party of their son, Parth, last week," uses "served," the past tense of "serve," aligning the verb tense with the time the event occurred.
· This adjustment ensures grammatical consistency and clarity in the narrative.
