And you think ... ?

-ar is the base form of these verbs, yes. So you must change the ending, true. HOWEVER, do subjects always have to be pronouns?

oh yeah, it's actually c

The correct answer for conjugating an -ar verb would be c. The ending needs to change for the subject.

To conjugate an -ar verb in Spanish, you need to change the ending of the verb to match the subject. Here's a step-by-step guide on how to do it:

1. Identify the -ar verb you want to conjugate. For example, the verb "hablar" (to speak).

2. Remove the -ar ending from the infinitive form of the verb, leaving you with the stem. In this case, the stem is "habl-".

3. Determine the subject of the sentence (e.g., yo, tú, él/ella, nosotros/as, vosotros/as, ellos/ellas).

4. Add the appropriate ending to the stem based on the subject. Here are the endings for each subject:

- Yo: -o
- Tú: -as
- Él/Ella/Usted: -a
- Nosotros/Nosotras: -amos
- Vosotros/Vosotras: -áis
- Ellos/Ellas/Ustedes: -an

For example, if you want to say "I speak," you would start with the verb "hablar," remove the -ar ending to get the stem "habl-," and then add the appropriate ending "-o." The conjugated form would be "hablo."

In summary, when conjugating an -ar verb, you need to change the ending of the verb to match the subject pronoun.
