Question

Use the correct reflexive pronoun. IF NO PRONOUN IS NECESSARY, CHOOSE THE X.

Answer 1

The answer is x. You can simply say cuando lavo el coche, no uso detergente. You could technically choose "te" but it doesn't make sense.

Answer 2

Answer:

Cuando lavo el coche, no uso detergente. The correct answer is "X", no pronoun is necessary.

Explanation:

Cuando lavo el coche, no uso detergente. In English: when I wash the car, I don't use detergent. The reflexive pronoun would be necessary if the sentence was about something related to someone. For example: "cuando me lavo la cabeza, no uso mucho shampoo". This means: when I wash my hair, I don't use much shampoo. Here we must use a pronoun, otherwise the sentence would lack sense. And it could be another pronoun, depending on whose hair is it. For example: "cuando te lavo la cabeza, no uso mucho shampoo". Meaning: when I wash your hair, I don't use much shampoo.
