Critical Reasoning

In Patton City, days are categorized as having heavy rainfall (more than two inches),
moderate rainfall (more than one inch, but no more than two inches), light rainfall (at least a
trace, but no more than one inch), or no rainfall. In 1990, there were fewer days with light
rainfall than in 1910 and fewer with moderate rainfall, yet total rainfall for the year was 20
percent higher in 1990 than in 1910. If the statements above are true, then it is also
possible that in Patton City

A. the number of days with heavy rainfall was lower in 1990 than in 1910
B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as
in 1910
C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than
in 1910
D. the total number of inches of rain that fell on days with moderate rainfall in 1990 was more
than twice what it had been in 1910
E. the average amount of rainfall per month was lower in 1990 than in 1910

Answer not given
I think its D

Can anyone clarify and explain the reasoning involved?

In the above question,

A - It is eliminated as number of days of heavy rainfall should be more instead of less to strenghten the argument (as in the option)
B - Contradictory
C - Contradictory
D- Compares the amount(inches) of rainfall on days with moderate rainfall.
The amount of rainfall on days with moderate rainfall in 1990 was more than twice what it had been in 1910 can be true as in the argument it is mentioned that total rainfall for year 1990 was 20% higher than in 1910.
E - Should be the opposite to be true
