Solution
The correct option is B Etiolation
Chlorosis occurs due to the lack of Fe, Mg. Necrosis occurs due to the lack of N, S, Mo. Shortening of internodes occurs due to lack of K. Whereas, etiolation is the phenomena which occur in plants not due to deficiency of any mineral element but when the plant is grown in partial or in the complete absence of light. It results in weak stems and loss of chlorophyll from the leaves. Thus the correct answer is option B.
