Solution

The correct option is A Test cross
A test cross has to be conducted to find out whether the plant is homozygous dominant or heterozygous dominant.

In test cross, the plant showing dominant phenotype for a particular character (and whose genotype is to be determined) is crossed with the recessive individual for the same character.

Back cross refers to the crossing of F1 hybrid with any of its parents.

Crossing of F1 hybrid with the dominant parent is called out cross.
