Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R).\n\n **Assertion (A):** Tertiary coal deposits of Northeast India are highly prized for metallurgical coke production in steel plants.\n **Reason (R):** Tertiary coal contains a high percentage of sulfur and volatile matter, making it unsuitable for direct metallurgical reduction without extensive processing.\n\n In the context of the above statements, which of the following is correct?

Options:

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