Correct Answer: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

Solution : The correct answer is (b) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

The assertion is true. Centralization of authority can lead to quicker decision-making because decisions are made by a select few at the top of the hierarchy. There's no need to consult or coordinate with various levels of management, which can expedite the decision-making process.

The reason, while true, does not provide the correct explanation for the assertion. While it's accurate that centralization reduces the need for coordination among different levels of management, this does not necessarily lead to quicker decision-making. The assertion is more directly related to the concentration of decision-making power at the top, rather than the reduction in coordination.
