Solution

The correct options are
B dominant
D F2
When a pure breeding tall plant is crossed with a pure breeding short plant, all the offsprings referred to as $F_{1}$ generation will be tall. So, it was concluded that dominant traits were expressed in the $F_{1}$ generation. When the $F_{1}$ generation plants were allowed to self pollinate or cross- pollinate with other, they produced $F_{2}$ generation with a chance of 3/4 of the plants being tall and 1/4 being short. So, it was concluded that the recessive character will be only expressed in $F_{2}$ and subsequent generations.
