Solution

## The correct option is B 11 timesWhen the time is below 6 the hour hand and minute hand will be 2 times in a straight line but opposite to each other. As the clock turns 6, the minute hand will fall and hence, they will be on same side.Thus, total number of times they are opposite and in straight line is 11.
