Choose the correct conjugation you walk (caminar)

caminas

O caminamos

camino

caminan

O

The answer is the first option "caminas".

Explanation:

When we conjugate the verb caminar (to walk) in the indicativo presente mood in Spanish, this is what we have:

yo camino

tú caminas

él/ella camina

nosotros caminamos

vosotros camináis

ellos/ellas caminan

Therefore, if the question wants us to conjugate it as "you walk" in English, we will have "tú caminas" in Spanish, since tú = you. Since the conjugation is enough to show to which person (first, second, or third; singular or plural) the verb refers, we may very well leave out the pronoun "tú", and say only "caminas".
