The correct option is B Only I is incorrect
Humans knew about hidden secrets of variations that arose as a result of sexual reproduction as long as 8000-1000 B.C. and have used it to develop various plant varieties and animal breeds by selective breeding, artificial selection, and hybridisation so that the progeny have desired traits.
Sources of variations can include mutations, sexual reproduction, etc. Mutations refer to any changes that occur in the sequence of DNA of an organism.
