Answer: (B) Pre-zygotic; post-zygotic.
Explanation:
Prezygotic isolation occurs before fertilization of eggs. It occurs between the two sex gametes and deter sexual reproduction between different species.
However, individuals are considered to be diverge on the phylogeny tree and different species, when they cannot reproduce.
Mechanisms of prezygotic isolation include habitat isolation, gamete isolation, mechanical isolation, behavioral isolation, and mating seasons.
Whereas, postzygotic isolation prevents the formation of fertile offspring. This phenomenon leads to production of an hybrid offspring from different species and this is a form of speciation in nature.
Mechanisms of postzygotic isolation include hybrid inviability, hybrid breakdown, and hybrid sterility.

The neurons conduct impulses over relatively long distance in the body. This is facilitated by their long cytoplasmic extensions
Portuguese version:
Não falo português mas:
Uma solução é formada quando algo é adicionado ou dissolvido em um líquido. Você faz uma solução quando adiciona sal ou açúcar a um copo de água. ... Desde que um líquido seja feito de uma única substância, ele permanece puro e é chamado de líquido. Quando algo é adicionado a ele, ele se torna uma solução.
English version: I don't speak Portuguese but:
A solution is formed when something is added or dissolved in a liquid. You make a solution when you add salt or sugar to a glass of water. ... As long as a liquid is made of a single substance, it remains pure and is called a liquid. When something is added to it, it becomes a solution.
Spanish version: No hablo portugues pero:
Se forma una solución cuando algo se agrega o se disuelve en un líquido. Usted hace una solución cuando agrega sal o azúcar a un vaso de agua. ... Mientras un líquido esté hecho de una sola sustancia, permanece puro y se llama líquido. Cuando se le agrega algo, se convierte en una solución.
fReNcH vErSiOn: Je ne parle pas portugais mais:
Une solution se forme lorsque quelque chose est ajouté ou dissous dans un liquide. Vous faites une solution lorsque vous ajoutez du sel ou du sucre à un verre d'eau. ... Tant qu'un liquide est constitué d'une seule substance, il reste pur et s'appelle un liquide. Quand quelque chose y est ajouté, cela devient une solution.
