El indica 9: 05. semáforo maleta reloj carro

El reloj indica 9:05.

Explanation: The word "reloj" in Spanish means "clock" in English. This is the word that fills in the blank because the incomplete sentence in Spanish ("El indica 9:05") can be translated as "The marks 9:05". "Reloj" collocates with the verb "marks" and, most importantly, it is related to the context of the sentence. In contrast, the other options could not fill in the blank because they would not add coherence to the sentence ("semáforo" is "traffic light", "maleta" is suitcase and "carro" is car).
