Answers

Answer 1

Final answer:

The safest way to sit at a desk while typing is to keep the knees and hips at 90-degree angles and the wrists straight, as this aligns the center of gravity above the hips, promoting good posture and reducing the risk of back strain and muscle strain.

Explanation:

The safest way to sit at a desk while typing on the computer is described in option A: Keep the knees and hips at 90-degree angles and the wrists straight. This position aligns the person's center of gravity above the pivot point in the hips, which is ideal for maintaining good posture and avoiding back strain and damage to the disks.

It is essential to ensure that the monitor is at eye level to avoid neck strain, and the keyboard should be positioned in such a way that the wrists remain straight to prevent muscle strain. Special ergonomic chairs can assist in achieving this posture by making it easier to position the body's center of gravity correctly.
