Answer 1

The correct option is B I - B, II - A, III - D, IV - C

Sympatric speciation is the process through which new species evolve from a single ancestral species while inhabiting the same geographic region.

Allopatric speciation or geographic speciation is a speciation, that occurs when biological populations of the same species become isolated from each other to an extent that prevents or interferes with genetic interchange.

The mechanisms of reproductive isolation or hybridization barriers are a collection of mechanisms, behaviors and physiological processes that prevent the members of two different species that cross or mate from producing offspring, or which ensure that any offspring that may be produced are sterile.

The Dobzhansky-Muller model proposes that reproductive incompatibilities between species are caused by the interaction of the genes of the respective species. Mecham's classification is one of the isolation classification. Thus, option B is correct.
