Choose whether the following sentences would use ser or estar.

Mis amigas _________ hablando por teléfono.

están

The verb "hablando" indicates a temporary or ongoing action, so the correct verb to use in this sentence is "estar." Therefore, the sentence would be:

Mis amigas están hablando por teléfono.

To determine whether to use "ser" or "estar" in the sentence, we need to consider the context and the specific meaning we want to convey.

In this case, the verb "hablando" indicates an action in progress or ongoing, which suggests that we should use the verb "estar" to indicate the temporary state or condition of the action.

Therefore, the correct form would be:

Mis amigas están hablando por teléfono.
