Critical Reasoning

A recent survey found that more computers than copies of computer programs were purchased by Germans last year. The best interpretation of this finding is that the practice of illegally duplicating commercial computer programs is widespread among Germans.

Each of the following, if true, would counter some reasonable objection to the interpretation advanced above EXCEPT:

(A) Few German computer users write their own computer programs.
(B) There are few free noncommercial computer programs available in Germany.
(C) Some Germans purchase computers outside of Germany for use in Germany, and such purchases were counted in the survey.
(D) The typical German computer user has several commercially written computer programs on his or her computer.
(E) Many Germans legally make duplicates of commercial computer programs, but such duplicates were counted as purchased copies in the survey.

Can some experts give me a line of reasoning for the best option?
