Although fullerenes--spherical molecules made entirely of carbon--were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite. Since laboratory syntheses of fullerenes reuires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's curst at tht time these naturally occurring fullerenes were formed.

Which of the following, if true, most seriously undermines the argument?

A) confirming that the shungite genuinely contained fullerenes took careful experimentation

B) some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft

C)The mineral shungite itself contains large amounts of carbon, from which the fullerenes apparantly formed

D) The naturally occurring fullerenes are arranged in a previously unknown crystalline structure

E) Shungite itself is formed only under distinctive conditions

IMO its B, It gives one more reason for formation of fullerenes and that does not relate to the state of the Earth's crust

I think it is B.
D doesn't make any sense.

Conclusion:
the discovery of natural fullerenes should give geologists a test case for evaluating hypotheses about the state of the Earth's curst at tht time these naturally occurring fullerenes were formed.

D says this natural fullerenes is different from the one's tested in laboratary before and therefore property of laboratary fullerenes (distinctive conditions of temperature and pressure) may not apply to them.
