Solution
The correct option is B 1, 2, 3 and 4 Speciation is the process of formation of new species. Change in chromosomal numbers will result in reproductive isolation. Geographical isolation and reproductive isolation stops the organisms from interbreeding. This might lead to speciation.
Competition for food leads to competition for habitat. This results in change in habitat for some individuals of the species eventually leading to speciation.
