Choose the correct imperfect form of 'ser' for the subject 'vosotros'.

Choose the correct imperfect form of 'ser' for the subject 'vosotros'.

• A. eras
• B. erais
• C. eran
• D. éramos

Answer: (B)

The main concept here is how the imperfect tense of the irregular verb ser matches the subject. In imperfect, ser is irregular: era, eras, era, éramos, erais, eran. For vosotros, which is the plural informal “you” in Spain, the form is erais. So erais is the form that aligns with the vosotros subject, describing a past ongoing state or habit. Other forms reflect other subjects: eras corresponds to tú, era to él/ella/usted, éramos to nosotros, and eran to ellos/ustedes. Those don’t fit the vosotros subject, so erais is the correct choice.
