The correct answer is A. 3:5.
The ratio of the width of the Indian national flag to its length is 3:5. The flag is rectangular in shape and has three horizontal stripes of equal width, saffron at the top, white in the middle, and green at the bottom. In the center of the white stripe is a blue wheel with 24 spokes, which represents the wheel of the Ashoka Chakra, a symbol of peace and prosperity.
The saffron color represents courage, sacrifice, and the spirit of renunciation. The white color represents peace and purity. The green color represents faith and fertility. The blue wheel represents the wheel of the law of dharma, which is the guiding principle of life.
The Indian national flag was adopted on 22 July 1947, the day India gained independence from British rule. The flag was designed by Pingali Venkayya, a freedom fighter from Andhra Pradesh.
