Tested the answers - I believe the answer is B - "-3" - took 1:10
Started with E - 0
11/10^0 = 11 - does not work
11/10^1 = 11/10 - does not work
11/10^2 = 11/100 > 10/100 - does not work
11/10^3 = 11/1000 - works, the answer is "-3"

Just putting values, the LHS becomes
n=0 --> 11
n=-1 --> 11/10
n=-2 --> 11/100
n=-3 --> 11/1000
Anything lower will be smaller than 11/1000. n=-2, equality doesnt hold but it does for n=-3.
Answer is B.
