विकल्प

• A is True and R is False.

• A is False and R is True.

• Both A and R are True.

• Both A and R are False.

Answer 1

Both A and R are True.

A is true. Iodine is a stain that improves the visibility of cell features, particularly the nucleus. R is false. The nucleus does not contain starch. The blue-black reaction involves starch, not the nucleus.
