The correct answer is option 2: 24 spokes. The Dharma Chakra, which is found in the center of the National Flag of India, represents the wheel of law and principles of Dharma. It is a symbol of righteousness, progress, and dynamism.

Option 1: 22 spokes is incorrect. It represents a different number of spokes than what is actually on the Dharma Chakra.

Option 3: 18 spokes is incorrect. It also represents a different number of spokes than what is on the Dharma Chakra.

Option 4: 14 spokes is incorrect. This number does not match the actual number of spokes on the Dharma Chakra.

It is important to note that the number of spokes has symbolic significance but is not explicitly mentioned in the question.
