Correct Option (d) Reason : In round seeds (RR/Rr) Starch-Branching Enzyme-1 (SBE-1) is found but is absent from wrinkled seeds. In I seeds, a small DNA segment interferes with SBE-1 activity so that starch is not formed and free sugar gets accumulated. Resulting high osmotic pressure in rr seeds leads to shrinkage and wrinkling.
