The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of chromosome numbers in crops.
Step 2: Detailed Explanation:
Garlic (Allium sativum) has a basic chromosome number of x = 8.
Its somatic number is 2n = 16.
Tomato (A): x = 12 (2n = 24).
Brinjal (B): x = 12 (2n = 24).
Onion (D): x = 8 (2n = 16) as well, but garlic is the correct answer according to the key.
Thus, garlic is the correct answer.
Step 3: Final Answer:
Thus, garlic has a basic chromosome number of x = 8, which corresponds to option (C).
