SEER Training: Introduction to the Muscular System training.seer.cancer.gov Nearly all movement in the body is the result of muscle contraction. Exceptions to this ... Posture, such as sitting and standing, is maintained as a result of muscle contraction.

Yes, the correct answer is B. Such as sitting and standing.

Posture, also known as body alignment, refers to the position and alignment of the body parts in relation to each other. It is maintained through muscle contraction, which helps to support and stabilize the body in different activities and positions.

In this question, option B correctly lists sitting and standing as examples of activities that require maintaining proper posture. Sitting and standing both require muscle contraction to keep the body upright and maintain proper alignment of the spine, hips, and other body parts.

Option A, such as singing and painting, and option C, such as jumping and skipping, are not directly related to maintaining posture. While these activities may require some level of muscle engagement, their primary focus is not on maintaining body alignment.

Option D, "All of the above," is incorrect because only option B, sitting and standing, is directly related to posture maintenance through muscle contraction.
