d bad posture reduces stress on joints and tendons.

please select the best answer from the choices provided.

a
b
c
d

Explanation:

• Option A: Poor posture typically causes muscle strain/tension, not "light muscles", so A is incorrect.
• Option B: Poor posture (like slouching or incorrect alignment) can hyperextend the spinal column, putting stress on it and leading to back pain. This makes sense.
• Option C: Poor posture generally decreases back flexibility, not increase it, so C is incorrect.
• Option D: Poor posture increases, not reduces, stress on joints and tendons, so D is incorrect.

Answer:

B. Bad posture hyperextends the spinal column.
