The correct answer is: d) Karana Mudra
The gesture you described is known as Karana Mudra, which is a hand gesture used in yoga and meditation practices to expel negative energy and purify the mind. To create the Karana Mudra, the hands are placed in front of the chest with the palms facing outward and the fingers extended. The index and middle fingers are then bent down and pressed against the palms, while the other fingers are held straight. This mudra is often accompanied by the visualization of light or energy being emitted from the hands, and is believed to help clear the mind and create a sense of balance and calm. It is often used as part of a meditation practice or as a way to prepare the mind and body for yoga or other physical practices.
Uttarbodhi Mudra, Dharma Chakra Mudra, and Varada Mudra are all different hand gestures with their own specific meanings and uses.
