In the given sentence, identify the segment which contains the grammatical error.
All the ladies of the colony assemble in the temple and prays together on Sunday evenings.

Correct option is B

Option (b) contains an error.
The verb "prays" is incorrect because the subject "ladies" is plural. The correct verb form should be "pray" to agree with the plural subject.
Correct sentence: All the ladies of the colony assemble in the temple and pray together on Sunday evenings.
Grammatical rule used:
• In subject-verb agreement, plural subjects take plural verbs without an “-s” ending in the present simple tense.
• "He prays" (singular) vs. "They pray" (plural)
Example:
Incorrect: The children plays in the park.
Correct: The children play in the park.
Information Booster:
Verbs ending in “-s” in present simple tense are used only with third-person singular subjects.
