Choose the correct answer:

- B.

- C.
how my brother's
- D.
behaviours has changed
(Correct Answer)
behaviours has changed
Explanation
To identify the error, we must examine the subject-verb agreement and the appropriate use of the noun "behaviour" in this context.
1. Identifying the grammatical mismatch:
The sentence uses the plural noun "behaviours" combined with the singular auxiliary verb "has".
In English grammar, "behaviour" is typically treated as an uncountable (mass) noun when referring to a general manner of acting. Therefore, the singular form "behaviour" should be used, requiring the singular verb "has."
If we define the relationship between the subject S (behaviour) and the verb V (has changed), the condition for grammatical correctness is:
Ssingular⟹Vsingular
Behaviour⟹has changed
2. Error Analysis:
The word "behaviours" is incorrectly pluralized in this specific context, and "has changed" is grammatically tied to a singular subject.
Part (d), "behaviours has changed," contains the disagreement because "behaviours" (plural) does not agree with "has" (singular).
Conclusion:
The error lies in part (d). The sentence should be corrected to: "I was shocked to see how my brother's behaviour has changed."
