Solution

The correct option is B 12
The bells will ring at the least common multiple of 4 and 6.
Multiples of 4 = 4, 8, 12, 16.....
Multiples of 6 = 16, 12, 18, 24.....
We can observe that 12 is the least common multiple of 4 and 6.
So, starting from 0 seconds the bells will ring after 12 seconds.
