Correct option is D
· Auxins are not primarily responsible for fruit ripening. Instead, ethylene is the major plant hormone responsible for fruit ripening. Hence, Statement I is incorrect.
· Fruits are classified into climacteric (e.g., banana, mango, tomato) and non-climacteric (e.g., grape, citrus, strawberry) based on their ripening process. This classification is correct, making Statement II correct.
· Therefore, option (d) is the correct answer.
