The only contenders are C and D.

C supports the stimulus. D remains. Likely answer. Lets reason it out with numbers.

Lets say 100 people in 1990 and 200 people in 2000. Rate of increase of pop = 100%
Lets says 10 beggars in 1990 and 18 beggars in 2000. Rate of increase of beggars = 80%
%age of beggars in 1990 = 10/100 = 10%
%age of beggars in 2000 = 18/200 = 9%

%age of beggars should have gone down. But D contradicts the stimulus since %age of beggars went up. Hence D is the answer.

Yeah stimulus is talking about "lower" rate. Not stalling or reversing.

My way of looking at it:

The passages states that the increase of beggars is less than than of the increase in general population, hence the ratio beggars/total population is decreasing.

D) Proportion (=ratio) increases which clearly contradicts the statement.

By assuming the following numbers, we can see that proportion decreases.
1950 P = 100, B = 10 Proportion = 10/100 = 0.1
1980 P = 130, B = 12 Proportion = 12/130 < 0.1 (Given that P's rate of increase is < that of B's)
D contradits by saying that proportion increased.

+1 D

If the proportion of beggars has increased, the total population has reduced or increased at a lower rate.
