Nosotros CONOCEMOS a Pablo.
The answer is this because CONOCEMOS comes from the word CONOCER meaning to know. CONOCEMOS means WE KNOW in Spanish. In this case, CONOCEMOS means WE KNOW (A PERSON) while SABEMOS means WE KNOW (SOMETHING). So, the answer is CONOCEMOS because in this case, it's a PERSON we know and NOT A THING/SOMETHING.
HOPE THIS HELPS!
HAVE A GR8 DAY ;-)
I think the answer is either A or C but I really think it's C
