A test cross is the crossing-xA0-of F1 progeny to the recessive parent- It is used to find genotype of the progeny- In the case of homozygous tall- all the progeny is obtained are tall while in the case of heterozygous tall- 1-2 is tall and 1-2 progeny is a dwarf-So- the correct answer is option D-

A test cross is the crossing of F1 progeny to the recessive parent. It is used to find genotype of the progeny. In the case of homozygous tall, all the progeny is obtained are tall while in the case of heterozygous tall, 1/2 is tall and 1/2 progeny is a dwarf.So, the correct answer is option D.

A common test to find the genotype of a hybrid is
Crossing of one $F_{2}$ progeny with female parent
Studying the sexual behaviour of $F_{1}$ progenies
Crossing of one $F_{2}$ progeny with male parent
Crossing of one $F_{1}$ progeny with recessive parent
