Find the erroneous part; if the sentence is correct, choose ‘‘No error.’’ Sentence: One of the objective of the meeting which was held today was to elect new office-bearers.

Introduction / Context:
This question checks subject–noun number agreement in the ‘‘one of the + plural noun’’ pattern.

Given Data / Assumptions:

• Headed by the quantifier phrase ‘‘one of the …’’
• Noun following ‘‘of the’’ must be plural.

Concept / Approach:
The correct structure is ‘‘one of the + plural noun’’ (e.g., ‘‘one of the reasons,’’ ‘‘one of the objectives’’). Using a singular noun after ‘‘of the’’ is ungrammatical.

Step-by-Step Solution:
Spot pattern: ‘‘one of the objective’’ → noun must be plural.Correct form: ‘‘one of the objectives’’.Recast: ‘‘One of the objectives of the meeting which was held today was to elect new office-bearers.’’

Verification / Alternative check:
Replace ‘‘one’’ with ‘‘two’’; you would naturally say ‘‘two of the objectives’’—confirming the noun needs to be plural.

Why Other Options Are Wrong:
B–D are fine and idiomatic; the only structural error is in A.

Common Pitfalls:
Letting the singular idea of ‘‘one’’ pull the following noun into singular form; forgetting that ‘‘of the’’ governs the plural set from which one item is selected.

Final Answer:
One of the objective
