Introduction:
This question tests verb + object patterns. Some verbs do not take an additional preposition before a direct object.

Given Data / Assumptions:

• Verb: "answer".
• Object: "the question".
• Extra preposition: "to".

Concept / Approach:
The verb "answer" is a transitive verb that takes a direct object without a preposition: "answer the question", not "answer to the question".

Step-by-Step Solution:
1) Identify verb: answered.2) Check valency: "answer" + direct object (no preposition).3) Detect error: presence of "to" between verb and object.4) Correction: "The student answered the question asked by the Inspector."

Verification / Alternative check:
Compare with similar verbs: "discuss a plan" (not "discuss about a plan").

Why Other Options Are Wrong:
A: Proper subject noun phrase.C: Correct direct object.D: Correct reduced relative clause.

Common Pitfalls:
Overgeneralizing prepositions after transitive verbs.

Final Answer:
B (Delete "to")
