Special underwear worn by the Sikh Khalsa represents alertness and readiness to fight.
According to the Sikh Code of Conduct, "For a Sikh, there is no restriction or necessity as to dress except that he must wear Kachera and turban."
Kachera is a drawer-style garment that is usually worn as underwear and is fastened by a fitting string around the waist.
Gobind Singh gave his Sikh followers this Kakkar as a reminder to restrain their urges to enter into a relationship (lust).
The purpose of the above-the-knee kachera is to offer the wearer a sense of honor, modesty, and respect.
The typical material for the outfit is white, breathable cotton. It covers the genitalia and helps to remind the Sikh to follow the Guru's directive to treat people of the other gender with respect.
Hence, option B is correct.
