Conjugate trabajar in the imperfect for the subject usted.

Conjugate trabajar in the imperfect for the subject usted.

• A. Trabajabas
• B. Trabajábamos
• C. Trabajaba
• D. Trabajaban

Answer: (C)

Imperfect tense for -ar verbs uses the endings -aba, -abas, -aba, -ábamos, -abais, -aban. For usted, which is treated like él/ella, the ending is -aba. So trabajar in the imperfect for usted becomes trabajaba. This form signals a past habit or background past action for usted. The other forms correspond to different subjects (tú, nosotros, ellos/ustedes), which is why they don’t fit with usted.
