Explanation Explanation for the correct answer: Option (c) is given that the axons going from one side to another side of the spinal cord within the gray matter are located in the gray commissures. The gray commissures consist of axons, which are crossing to the opposite side of the spinal cord. Hence, option (c) is correct. Explanation for incorrect answers: Option (a) is given that the axons going from one side to another side of the spinal cord within the gray matter are located in the anterior horns. The anterior horns are involved in controlling the muscles of both the lower and upper limbs. So, it is an incorrect option...
