Given below are two statements, one labeled as Assertion (A) and the other as Reason (R). **Assertion (A):** Skeletal muscle glycogen cannot be directly used to elevate blood glucose levels during periods of fasting. **Reason (R):** Skeletal muscle cells lack the enzyme glucose-6-phosphatase, which is required to convert glucose-6-phosphate into free glucose. Choose the correct option in light of the statements:

Options:

• A: Both A and R are true but R is not the correct explanation of A.
• B: Both A and R are true and R is the correct explanation of A.
• C: A is true but R is false.
• D: A is false but R is true.
