E) Question 5: La puerta está al lado _________sillas. (1 point)

de los
del
de las
de la

de las

To determine the correct answer to this question, we need to understand the rules of Spanish prepositions. In this sentence, "al lado" means "next to" or "beside" in English. The preposition "al" is a combination of the preposition "a" ("to" or "at") and the article "el" ("the" in masculine singular form).

Based on the word "sillas," which is plural, we can eliminate the options "del" and "de la" since they both use the singular form of the article.

The correct answer is "de las" because it uses the plural form of the article "las" ("the" in feminine plural form) to agree with the plural noun "sillas". Therefore, the sentence should be "La puerta está al lado de las sillas."

To answer this question, you need to choose the correct preposition and article to complete the sentence.

The correct answer is "de las."

So the complete sentence would be "La puerta está al lado de las sillas." (The door is next to the chairs.)
