What is the correct tense to be used with reflexive verbs?

Question

The following sentence was put in the TRANSLATION unit: " I slipped on the ice and fell to the ground." The 3 translations returned were:

1. Me resbalé en el hielo y cayó al suelo.
2. Resbalé en el hielo y me caí al suelo.

3. Me deslicé en el hielo y me caí a la tierra.

   Now there are 3 reflexive verbs in these answers but, the tenses don't seem to agree? What am I missing here?

Answer 1

cayó and caí are from preterite tense of the infinitive caer = to fall cayó is 3rd person singular while caí is first person singular: el, ella, usted cayó yo caí so I think the correct translation is : Me resbalé en el hielo y me caí al suelo.

Answer 2

One clue: the tenses are correct. But one of the options has two different persons.

Answer 3

Tense has nothing to to with it (they're all simple past). The only issue is the pronouns (subject and, perhaps reflexive) .
