Final answer:
The correct option in this question is: Mina regresó temprano a casa de la escuela porque no se sentía bien.
Step-by-step explanation:
The correct option in this question is: Mina regresó temprano a casa de la escuela porque no se sentía bien. This option correctly uses a comma splice to connect two independent clauses together. A comma splice is when two independent clauses (complete thoughts) are joined together using only a comma. In this case, 'Mina regresó temprano a casa de la escuela' and 'no se sentía bien' are connected using a comma to indicate a cause-effect relationship between the two actions.
Using a comma splice is a common mistake in writing. Instead, it is recommended to use a coordinating conjunction like 'because' to connect the two independent clauses, as shown in the correct option.
Remember that in Spanish, it is important to use the appropriate punctuation, especially when it comes to joining clauses together.
