Final answer:
The correct verb form is "colocamos."
Step-by-step explanation:
The correct verb form to complete the sentence "Nosotros ________ las copas sobre la mesa" is "colocamos."
"Colocamos" is the first person plural form of the verb "colocar," which means "to place" or "to put." It matches the subject "nosotros," which means "we."
For example: "Nosotros colocamos las copas sobre la mesa antes de la cena." (We place the glasses on the table before dinner.)
