Answer Details

If the shoot tip of a plant is cut off and replaced by an agar block containing auxin, the plant will grow rapidly. This is because auxin is a plant hormone that promotes cell elongation and division. When the shoot tip is cut off, the plant loses its source of auxin, which normally inhibits the growth of lateral buds. By replacing the shoot tip with an agar block containing auxin, the plant is provided with a source of the hormone that stimulates the growth of the lateral buds, leading to the rapid growth of the plant. Therefore, is the correct answer.
