The intensity level of a sound is reported in unit decibel(dB). how does IL change if we increase a sound intensity by a factor of 10?

a)remains the same
b) increases by 1dB to 2dB
c)it increases by 2dB to 20dB
d)it increases by 20dB to 200dB
e) it decreases

equations...
IL=10(log I- logIo)

I am very confused as to how to go about solving this problem...any help would be greatly appreciated.

    "None of the above" should be a choice

    The sound intensity (power/area) increases by a factor of 10 whenever the I.L. increases by 10 dB
