Answer:
[tex]\boxed {\sf D. \ Ellas \ responden}[/tex]
Explanation:
We want to conjugate they (feminine) respond.
In Spanish, the feminine they is [tex]\sf Ellas[/tex]. So, we can eliminate the second choice, because it is ellos.
The verb for respond is [tex]\sf responder[/tex]. We want to conjugate for ellas.
1. Drop the ending.
- The ending is -er, so drop it.
- [tex]\sf Responder[/tex]⇒[tex]\sf Respond[/tex]
2. Add the correct verb ending.
- For ellos/ellas/ustedes and -er verbs, the ending is [tex]\sf -en[/tex].
- [tex]\sf Respond[/tex]⇒[tex]\sf Responden[/tex]
Therefore, the correct answer is Ellas responden.
