Answer: The correct answer is-

Allopatric- option 2.

Sympatric - option 1.

Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).

In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.

On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.

Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.
