Final answer:
The correct translation is B) They made their bed (Completed action).
Step-by-step explanation:
The correct translation for 'Ellos hicieron su cama' is option B) They made their bed (Completed action).
In this sentence, 'hicieron' is the past tense of the verb 'hacer' which means 'to make' or 'to do'. The use of the past tense indicates that the action of making the bed has already been completed.
This sentence does not describe the state of the bed (option A), but rather emphasizes the action of making the bed in the past.
The correct translation of 'Ellos hicieron su cama' would depend on the context of the sentence in Spanish, especially if the past tense used is emphasizing a completed action or simply stating a fact as a description.
Since 'hicieron' is the past tense of 'hacer' in Spanish, which means 'to make' or 'to do', and is used here to describe an action completed in the past, the correct translation would be option B) They made their bed (Completed action). This indicates that the action of making the bed has been completed by 'ellos', which, in English, refers to 'they'.
