Question

Choose the best conjugation.

they (feminine) respond

ellas responder
ellos responden
ellas respondan
ellas responden

Answer 1

The answer is the second one...Ellas responden

Answer 2

`\boxed {\sf D. \ Ellas \ responden}`

Step-by-step explanation:

We want to conjugate they (feminine) respond.

In Spanish, the feminine they is
`\sf Ellas`. So, we can eliminate the second choice, because it is ellos.

The verb for respond is
`\sf responder`. We want to conjugate for ellas.

1. Drop the ending.

• The ending is -er, so drop it.

• 
  `\sf Responder`⇒
  `\sf Respond`

2. Add the correct verb ending.

• For ellos/ellas/ustedes and -er verbs, the ending is
  `\sf -en`.
• 
  `\sf Respond`⇒
  `\sf Responden`

Therefore, the correct answer is Ellas responden.
