Answer: Option C.
High-energy waves like UV light or radiation physically damage the DNA
Explanation:
Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.
Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.

Answer:
The three stimuli that cause the plants to exhibit tropism are:
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.
3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.
