The correct option is A
TT X tt
$↓$
Tt (F1 generation)
For F2 generation, F1 X F1
Punnet Square of F2 generation,
$\begin{matrix} T & t T & T T & T t T a l l & T a l l t & T t & t t T a l l & d w a r f \end{matrix}$
From the table above we can infer that the ratio of dwarf plants in F2 generation will be $25 %$ .
