Solution

The correct option is A
220, 440 and 660

Common multiples of any given set of numbers will always be the multiples of the LCM of the numbers.

Now, LCM of 4, 5 and 11 can be found as follows.
Hence, LCM = $2 \times 2 \times 5 \times 11 = 220$
The multiples of 220 are 440, 660, 880...

Hence, in the given options, the common multiples of 4, 5 and 11 are 220, 440 and 660.
