    Assertion (A): Carbon is the only chemical element that forms the largest number of compounds.

    Reason (R): Carbon possesses a special property called catenation.

    A Both (A) and (R) are true, but (R) is not the correct explanation for (A). Correct Answer Incorrect Answer
    B Both (A) and (R) are true and (R) correctly explains (A). Correct Answer Incorrect Answer
    C (A) is true, but (R) is false. Correct Answer Incorrect Answer
    D (A) is false, but (R) is true. Correct Answer Incorrect Answer

    Solution

    Carbon's ability to form chains and rings of different sizes allows it to create a vast number of compounds. This characteristic is known as catenation. So, (R) is true. However, hydrogen forms the largest number of compounds. So, (A) is false.   Hence, the correct answer is (D).
