Answer:
1. Comparte
Step-by-step explanation:
Ella comparte la pizza y las papas fritas.
Translation:
She shares pizza and french fries.
As for the third and fourth option (write and write respectively) they do not make sense therefore they are discarded .
The correct word comes from the verb "compartir" (inifinitive). Therefore we have to know the person and the time that the action is performed to achieve the correct conjugation of the verb in Spanish.
In this case it is her, therefore third person of the singular and the time is present. so the verb "compartir"" (inifitive) is conjugated "comparte" (3rd person singular in the present)
