Answer:
The answer is A. XIV y XV
Step-by-step explanation:
The Spanish language is a Romance Language, which are modern languages that evolved from Vulgar Latin. Spanish extended throughout the Iberian Peninsula during the Late Middle Ages (XIV and XV centuries), thanks to the continuous expansion of the Christian Kingdoms, in the period known as the Reconquista (reconquest). The incorporation of the León and Galicia kingdoms to the Crown of Castile, and the introduction of a castilian dynasty to the Crown of Aragon, with Fernando I de Aragon in 1410, and later on, the peninsular union with the Catholic Kings increased the assimilation and linguistic equalization of the dialects in the different kingdoms. By the XV century, the common Spanish language had been introduced in most of the Iberian peninsula. In 1492, it was first published Gramatica Castellana, the first Spanish language grammar work by Antonio Nebrija. Another important fact, mainly in Spain, was the discovery of America in 1492, which led to the spread of the language after the Spanish colonization of the Americas in the XVI century, and spread the Spanish language through most of the american continent.
