In this English grammar error-spotting question, identify which part of the sentence is incorrect in its use of the preposition after "elected": "He was elected (A) as chairman (B) of the college. (C) No Error. (D)". Choose the option that marks the erroneous segment or select 'No Error' if the sentence is fully correct.

Introduction / Context:
This question assesses your knowledge of standard English usage after certain verbs, especially the verb "elect" when it describes choosing someone for a position. The sentence talks about a person being chosen as chairman of a college committee or body. You need to decide whether the use of "as" in this context is correct or whether a more natural, idiomatic construction is required.

Given Data / Assumptions:

• Sentence: "He was elected as chairman of the college."
• Part A: "He was elected"
• Part B: "as chairman"
• Part C: "of the college."
• Part D: indicates that there is no error.
• The context is a formal election to a position or office.

Concept / Approach:
In standard formal English, the verb "elect" is usually followed directly by the office or position, without the preposition "as". For example, we say "He was elected chairman", "She was elected president", or "They elected him captain." While "elected as" may sometimes be heard in informal speech, most grammar and usage guides prefer the structure "elected + position" with no preposition. Exam questions follow this stricter standard and treat "elected as chairman" as incorrect.

Step-by-Step Solution:
Step 1: Analyse Part A: "He was elected". This is a correct passive construction in the simple past tense. Step 2: Analyse Part B: "as chairman". This segment introduces the position to which he was elected. However, the verb "elect" does not normally require "as" before the position in formal English. Step 3: The correct phrase should be "He was elected chairman", not "He was elected as chairman". Step 4: Analyse Part C: "of the college." This prepositional phrase correctly specifies the institution and is grammatically sound. Step 5: Since Parts A and C are correct, and Part B contains the nonstandard usage, Part B is the portion with the error.

Verification / Alternative check:
Rewrite the sentence in the recommended form: "He was elected chairman of the college." This version is standard and often appears in newspapers, official reports, and textbooks. Compare it with "He was elected as chairman of the college", which sounds less precise and is typically not accepted in competitive exam grammar. This difference confirms that "as" should be removed in this context.

Why Other Options Are Wrong:

• Part A: "He was elected" correctly introduces the passive voice with no tense or agreement error.
• Part C: "of the college" is the correct prepositional phrase to describe the institution where he holds the position.
• Part D (No Error): Cannot be chosen because we have identified a definite usage issue in Part B.
• Error in more than one part: Incorrect because only the presence of "as" in Part B is problematic.

Common Pitfalls:
Many learners overuse prepositions such as "as" after verbs like "appoint", "elect", "consider", and "name". For example, "He was appointed as manager" or "She was elected as president" are common but not recommended in formal exam English. The concise forms "appointed manager", "elected president", and "named captain" are preferred. Paying attention to such fixed patterns improves both accuracy and fluency in written English.

Final Answer:
The incorrect segment is Part B: "as chairman"; the correct sentence is "He was elected chairman of the college.".
