Correct answer:
trajo
The simple present tense is used to talk about habitual actions or routines. This tense is also used to describe things that happen now or in the near future. On the other hand, the preterite tense is one of two simple past tenses. It is used to describe actions that took place or were completed at a certain point in the past. So trae is the conjugation of the verb traer for the third person singular in the simple present. On the other hand, trajo is the conjugation of the verb traer that matches the third person singular in the preterite. Finally:
SIMPLE PRESENT:
Carlitos trae el auricular a su mamá.
PRETERITE TENSE:
Carlitos trajo el auricular a su mamá.
