A. 20
B. 19
C. 22
D. 35
E. none of the above
Answer: C . 22


the hands of a clock point in opposite directions (in the same straight line) 11 times in every 12 hours. (Because between 5 and 7 they point in opposite directions at 6 o'clcok only).

So, in a day, the hands point in the opposite directions 22 times.
