Correct answer:
a. brazos
Brazos means arms and ojos means eyes. So you use your arms to give people hugs, not your eyes. On the other hand, doy is the conjugation of the verb dar that matches the first person singular in the simple present. 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. Finally:
Doy abrazos con mis brazos
