1. yo digo la verdad a vosotros.

2. nosotros decimos la hora a ellos.

a.) me
b.) les
c.) le
d.) nos

3. teresa de la camera a mi.

a.) le
b.) os
c.) te
d.) me

We need to complete the sentences with the right option:

1) Yo digo la verdad a vosotros.

There are two ways of complete this, the more "correct" one is "os"

Yo os digo la verdad a vosotros.

There is other more commonly used, is "le"

Yo le digo la verdad a vosotros.

2) Nosotros __ decimos la hora a ellos.

Here the subject is "ellos", so the righ answer is "les"

Nosotros les decimos la hora a ellos.

3) Teresa ___ de la cámera a mi.

i think there is a typo here, the sentence must be:

Teresa ___ dio la camara a mi.

Here the speecher is talking about how teresa gave the camera to him, so the right option is "me"

Teresa me dio la camara a mi.

i cant tell what you want but if you message me and tell me ill be glad to
