3. Grammar. Выберите правильный ответ. 3. On Sundays Jessica get up early. She .... stay in bed until 10 o'clock.

The correct answer is c. doesn't have to, can.

The first part of the sentence implies a choice or lack of obligation. 'Doesn't have to' indicates no requirement to get up early. The second part suggests permission or ability to stay in bed, for which 'can' is appropriate.
