**Answer: (1) 156**

**Explanation:-
**A clock ring an alarm bell once at 1, twice at 2 and thrice at 3,

Then, the clock will ring the alarm bell in 24 hours = 2 (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12)

= 2 x 78

= 156

Then, 156 time the clock will ring the alarm bell in 24 hours.

Hence, the answer is (1) 156.
