Solution

The correct option is C $F_{1}$ and $F_{2}$ generation

Mendel conducted hybridisation experiments on pea plants. He selected pure lines as parents. Pure lines are always homozygous. Crossing of parents results in $F_{1}$ generation.
The $F_{1}$ generation hybrids are heterozygous and exhibit the dominant phenotype only.

Selfing of $F_{1}$ hybrids results in $F_{2}$ generation in which individuals with both the dominant and recessive phenotypes are produced.

Yellow colour of seeds is dominant over green colour of seeds in pea plant.
Hence, plants with yellow seed colour are produced in both $F_{1}$ and $F_{2}$ generations.

Plants with green coloured seeds are produced in $F_{2}$ generation only as it is a recessive trait.
