Question

there are four standard rifle-firing positions. choose the steadiest.
a prone
b standing
c sitting
d kneeling

Explanation:

In rifle - firing, the prone position has the shooter lying on the ground. This position provides the most contact with the ground, which helps in minimizing movement and recoil. The body's center of gravity is low, and there is more surface area in contact with the ground (compared to standing, sitting, or kneeling), reducing the impact of external forces (like wind) and internal forces (recoil). Standing has the highest center of gravity and least contact with the ground, making it the least steady. Sitting and kneeling have more contact than standing but less than prone.

Answer:

A. prone
