Answer:
E. Van
Explanation:
The words "ellos" is present in this sentence, so we have to conjugate the word accordingly.
With situations like these, you conjugate words using the following endings:
Yo: -o
Tu: -as
El/Ella/Usted: -a
Nosotros: -amos
Vosotros: -ais
Ellos/Ellas/Ustedes: -an
Vosotros is only used in Spain though.
Since we are referring to they (male), we have to use the ending -an.
Therefore, the answer is E.
