Gregor Mendel is known for his experiments performed on the pea plants on the basis of which he was able to predict the principles of inheritance. He used seven different characters to understand the inheritance pattern of the traits in generations.
He performed monohybrid (single) and dihybrid (two) crosses by growing the plants from the seeds and performing cross-fertilization and self-fertilization. He performed self- fertilization by emasculation and cross-fertilization by shedding the pollen of another plant over ovules of another plant.
Thus, Option-C is the correct answer.

Explanation:
Various pigments present in the plants helps in the absorption of the light, at photosynthesis. They acts as helpers to the plants. Chlorophyll helps in the green plants for absorption of light through which they can prepare their own food. The electrons in the molecular level of chemical structure of the pigment moves at certain energy levels. The chlorophyll is again divided into different types i.e. chlorophyll a,b,c,d. In case of plants chlorophyll a and chlorophyll b are the most important.
