CorrectNot quiteAnswer A

Correct answer: A

Explanation

  1. From noon on 1 June to noon on 21 June is 20 days.

  2. Loss =20×9=180= 20 \times 9 = 180 minutes =3= 3 hours, so the clock shows 9:00 a.m.

Worth noting

3:00 p.m. adds the 3 hours; a slow clock is behind. 9:09 a.m. counts only 19 days.
