Answer:
[tex]\boxed {\tt A. \ Tiene}[/tex]
Explanation:
The sentence is:
Mónica_____ocho años (Monica _____ eight years)
The answer choices are all conjugated forms of tener.
Monica is one person and in this sentence is a "she". We must conjugate for el/ella/usted. Tener conjugated for ella is tiene.
So, the correct answer is A. tiene.
The completed sentence is:
Mónica tiene ocho años (Monica is eight years old).
