A certain computer program creates temporary files on the computer on which it is installed. The files contain a programming error, or "bug", that, in rare cases, may cause the computer to freeze up. The temporary files are purged 90 days after the program is installed. Since no program will copy the bug to any other file, any computer containing the program that freezes more than 90 days after the program has been installed does not freeze because of this bug.
Which of the following, if true, most seriously weakens the conclusion above?
A. A computer that freezes due to the installation of the program in question produces a display that is similar to that which is displayed when computers freeze for many other reasons.
B. The code that causes the freezing will be eliminated in a future release of the program.
C. Other bugs in the programming may reveal themselves more than 90 days after the program is installed.
D. A person can copy the programming code containing the bug to other files that are purged with less frequency than the temporary files.
E. There are some computers on which the program is installed that appear to be unaffected by the programming bug.
