Question

Fill-in the blank with the appropriate object pronoun: me, te, t', le, la, l', nous, vous, les. Coucou! Tu me vois? Oui, je _____ vois.

Answer 1

Hi,

Fill-in the blank with the appropriate object pronoun: me, te, t', le, la, l', nous, vous, les.

 Coucou! Tu me vois? Oui, je te vois.

Answer 2

Coucou! Tu me vois ? Oui, je ____ vois. - "Hello! Do you see me? Yes, I ____"

Reflexive pronouns - 
te - "you"
t' - "you" when the next word starts with a vowel (t'aime)
la - "the" feminine
l' - "the" when the next word starts with a vowel (l'eau)
nous - "we"
vous - "you" formal
les - "the" plural

Since the sentence is informal, the answer is:
Je te vois.

Hope this helps.
