Answer:
Ella ve una película.
Step-by-step explanation:
In the sentence "Ella ve una película," the verb "ver" is used in the present tense to match the subject "ella" (which means "she" in English).
In Spanish, the present tense form of the verb "ver" (meaning "to see" or "to watch") conjugates as follows:
Yo veo (I see/watch)
Tú ves (You see/watch)
Él/Ella/Usted ve (He/She/You formal see/watch)
Nosotros/Nosotras vemos (We see/watch)
Vosotros/Vosotras veis (You all see/watch)
Ellos/Ellas/Ustedes ven (They/You all see/watch)
Since the subject "ella" corresponds to the third person singular (he/she/you formal), we use "ve" as the present tense form of "ver" in this sentence.
So, "Ella ve una película" translates to "She watches a movie" or "She sees a movie" in English.
