If the minute hand of a clock points towards the South at 12:00 a.m., then in which direction will the minute hand point at 3:00 a.m. in the same clock?

South

If the minute hand of a clock points towards the South at 12:00 a.m., it means that the clock is oriented with the 12 at the bottom (6 at the top).

At 3:00 a.m., the hour hand of the clock will be pointing at the 3, and the minute hand will be pointing at the 12. Since the minute hand points south when it is on the 12, at 3:00 a.m., the minute hand will be pointing towards the South.
