Which option correctly matches a plant part with its usual response?
Answer and explanation
Correct answer: तना प्रकाश की ओर और जड़ गुरुत्व की दिशा में बढ़ती है
The governing concept is directional growth, or tropism. A shoot commonly shows positive phototropism and grows toward light, while a root generally shows positive gravitropism and grows in the direction of gravity into the soil. Therefore, option A is correct. The opposite claims in B are wrong, C uses animal structures that plants do not have, and D gives unsupported universal statements about tendrils and roots.
