Explanation:

Tight muscles can constrict nerves in the spinal column, leading to pain. Muscles themselves don't have the main characteristic of containing overly - sensitive nerves as described in A. Stretching surrounding tissues and organs (C) is not the main way tight muscles cause back pain. Improving posture (D) generally doesn't cause back pain but rather helps reduce it.
