Line 22 of the passage states:

"ALH84001 has been on earth for 13,000 years, suggesting to some scientists that its PAH’s might have resulted from terrestrial contamination."

If PAH has resulted from terrestrial contamination, then most likely it did not originate from Mars, that is, when the meteorite landed on Earth it did not contain PAH. Therefore, C is correct.

E directly contradicts line 22's statement by asserting that the organic molecules found in the meteorite could NOT have resulted from terrestrial contamination; therefore it is incorrect.
