(ii) and (iv)
C
(ii) and (iii)
D
(iii) and (iv)
Explanation: 

Detailed explanation-1: -Final answer: The correct sentences are hybridization means crossing between genetically dissimilar plants and ntroducing genes of the desired character into a plant gives a genetically modified crop .

Detailed explanation-2: -Hybridization refers to crossing between genetically dissimilar plants.

Detailed explanation-3: -This crossing may be intervarietal (between different varieties), interspecific (between two different species of the same genus) or intergeneric (between different genera).

Detailed explanation-4: -The mating or crossing of two plants or lines of dissimilar genotype are known as hybridization. Crossing involves placing pollen grains from one genotype, the male parent, on to the stigma of flowers of the other genotype, the female parent.
