Why are carbonaceous chondrites thought to be original material that formed in the early solar nebula?
A)   They show a Widmanstätten pattern, which indicates slow condensation from gaseous material.
B)   Their minerals contain up to 20% water, which would have evaporated away if the chondrite had been strongly heated.
C)   They consist mostly of carbon, which was the dominant substance condensing in the outer solar nebula.
D)   They consist almost entirely of ice, which would have sublimed away by now if this were not the first time the chondrite was passing close to the Sun.
