The correct answer for who designed the Indian flag is option 2, Pingali. It is important to note that Pingali Venkayya is the actual person who is credited for designing the Indian flag. He presented his design to Mahatma Gandhi during the All India Congress Committee meeting in 1921. The design was then modified and adopted by the Constituent Assembly of India on 22 July 1947 as the national flag of India. The flag consists of three horizontal stripes of saffron, white, and green, with the Ashoka Chakra in the center. The saffron color represents courage and sacrifice, the white color represents purity and truth, and the green color represents fertility, growth, and auspiciousness. The Ashoka Chakra is a depiction of the wheel of law and signifies righteousness, progress, and peacefulness. It is important to remember that while other individuals may have held important roles in the Indian independence movement, it was Pingali Venkayya who designed the Indian national flag.
