Answer 1

The correct option is A 1, 2 and 3

Development of the new variety of plant processing desirable characters from existing ones is known as plant breeding.

Plant introduction means introducing a plant having desirable characters which are a genetic improvement, high yield, disease resistance and vigorous growth from a region of a country where growth naturally to a region or a country where does not occur earlier.

Then the pure line selection is done.

Hybridization is a method of reducing new crop varieties in which two or more plants of unlike genetical constituents are fused together.

So, the correct option is '1, 2 and 3'
