The correct answer is: A. gallantry in the presence of enemy.
The Shaurya Chakra is a military decoration of India awarded for gallantry in the presence of the enemy. It is the third-highest peacetime gallantry award in India, after the Param Vir Chakra and the Maha Vir Chakra. The award was instituted on 26 January 1950, the first Republic Day of India.
The Shaurya Chakra is a circular bronze medal with a diameter of 35 millimetres. The obverse of the medal bears the national emblem of India, with the words “Shaurya Chakra” inscribed in Devanagari script below. The reverse of the medal bears the words “For Gallantry in the Presence of the Enemy” inscribed in English and Hindi. The medal is suspended from a green ribbon with a red and white stripe in the centre.
The Shaurya Chakra is awarded to officers and men of the Indian Armed Forces, as well as to civilians who have performed acts of gallantry in the presence of the enemy. The award is not limited to members of the Indian Armed Forces, and has been awarded to civilians on a number of occasions.
The Shaurya Chakra is a prestigious award, and is considered to be one of the highest honours that can be bestowed on an individual in India. The award is a symbol of courage and sacrifice, and is worn with pride by those who have been awarded it.
The other options are incorrect because they do not accurately describe the criteria for the award of the Shaurya Chakra. Option B, gallantry otherwise than in the face of the enemy, is the criteria for the award of the Vir Chakra. Option C, most conspicuous bravery for some act of self sacrifice, is the criteria for the award of the Ashoka Chakra. Option D, none of the above, is incorrect because it does not accurately describe any of the criteria for the award of the Shaurya Chakra.
