Read the following statements and choose the correct option.

Assertion: Uncertainty is reduced by planning.
Reasoning:. Uncertain occurrences or changes can be anticipated and avoided with proper planning.

Assertion (A) is true but Reasoning (R) is not correct.

The correct answer is option 3- Assertion (A) is true but Reasoning (R) is not correct.

Assertion: Uncertainty is reduced by planning. This is true.
Reasoning:. Uncertain occurrences or changes can be anticipated and avoided with proper planning. This is not true.

The assertion claims that uncertainty is reduced by planning. However, the reasoning suggests that uncertain occurrences or changes can be anticipated and avoided with proper planning. It's true that while planning can help anticipate and mitigate some uncertainties, it might not completely avoid all uncertainties. Some unpredictable events or changes may still occur despite thorough planning.
Thus, the correct answer is assertion is true but reason is not.
