The correct way to say "They are Colombian" in Spanish is "Son colombianos" (option a). The verb "ser" (to be) is used to describe nationality, so we would use the third person plural form, which is "son" (are). Additionally, in Spanish, adjectives like "colombianos" usually match the gender and number of the noun they are modifying, so we use the plural form as well.

To arrive at the correct answer, it helps to have some knowledge of Spanish grammar rules and vocabulary. In this case, knowing how to conjugate the verb "ser" in the present tense and recognizing the masculine plural form of the adjective "colombianos" is important. You can also consult a Spanish grammar book, online resources, or a language learning app like Duolingo to learn and practice the basics of Spanish grammar and vocabulary.
