AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The correct answer is (C) Kerala.
Rubber is mainly grown in Kerala, Tamil Nadu, Karnataka, and Andaman & Nicobar Islands. Kerala is the largest producer of rubber in India.
The question asks for the largest producer. The source passage lists Kerala first among rubber-growing states, and as per NCERT/standard data, Kerala dominates rubber production in India. Note that the answer options given in the MCQ do not perfectly match the original four lettered options — choose (C) Kerala as the answer. Examiners expect you to recall Kerala as the leading rubber-producing state.
