A)So, from above figure it is clear that when the hands are in opposite direction ,then they are 30 minutes space apart.B)Above figure shows when the hands are in same straight line and when they are co incident or opposite to each other.C)Third statement is wrong because if a clock indicates 8:45,when the correct time is 9:00 then, it is said too 15 minutes too slow.(If the clock indicates 9:15 and the correct time is 9:00 then, it is said to be 15 minutes fast.)Hence, option "3" is correct.
