The correct answer is D.

Explanation: The sentence "The chairman did not take kindly to the ____________ remarks about his policy." describes remarks that are critical or disrespectful towards the chairman's policy.

- D. derogatory is correct because "derogatory" refers to remarks that are intended to belittle or show a lack of respect, which fits the context of not taking kindly to negative comments about his policy.

Other options:
- A. abusive: This implies harsh or harmful language, which is more severe than what might be implied by "derogatory."
- B. dishonourable: This describes a lack of honor or integrity, which is not the most fitting term for comments about policy.
- C. derisive: This means expressing contempt or ridicule, which is close but slightly more specific to mocking rather than general disrespect.

Thus, "derogatory" best fits the context of not taking kindly to negative remarks about his policy.
