• D. $\begin{array}{ccccc}& A& B& C& D\\ \left(d\right)& 1& 2& 4& 5\end{array}$

Answer 1

The correct option is B $\begin{array}{ccccc}& A& B& C& D\\ \left(b\right)& 5& 4& 1& 3\end{array}$

Mutation breeding is a process by which genetic variations are created through changes in the base sequence within the gene. This results in the creation of new character or trait. It is a quick method.
Selection is a very age-old method where varieties are bred for selected characters/traits. It can also be called as artificial selection.
Hybridization is the process of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization). It a laborious and expensive method.
