Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the muscular system's primary functions. The muscular system is responsible for movement, posture, and heat production in the body.
2. Step 2: Analyze each option provided in the question. For example, 'Transmitting electrical impulses' is primarily a function of the nervous system, not the muscular system.
3. Step 3: Evaluate the option 'Filtering waste from the blood.' This is a function of the renal system (kidneys), not the muscular system.
4. Step 4: Consider the option 'Regulating hormone secretion.' This is a function of the endocrine system, which involves glands like the pituitary and thyroid.
5. Step 5: Recognize that 'Producing movement of the body' is the correct answer, as it aligns with the muscular system's primary role in facilitating voluntary and involuntary movements through muscle contraction.
