The correct answer is 15 degrees.

The clock is a circle and the hour hand moves around it every 12 hours. The clock is 360 degrees divided into 12 hours. So, it’s 30 degrees per hour.  The hour hand points exactly at the 6 at 6:00, so 30 minutes later, when the minute hand points at the 6, the hour hand is pointing at 6.5 or 15 degrees past 6.
