A group of unusual meteorites was found in Shergotty, India. Their structure indicates that they originated on one of the geologically active planets: Mercury, Venus, or Mars. Because of Mercury’s proximity to the Sun, any material dislodged from that planet’s surface would have been captured by the Sun, rather than falling to Earth as meteorites, nor could Venus be the source of the meteorites, because its gravity would have prevented dislodged material from escaping into space. The meteorites, therefore, probably fell to Earth after being dislodged from Mars, perhaps as the result of a collision with a large object.
The argument derives its conclusion by:
(A) offering a counterexample to a theory
(B) eliminating competing alternative explanations
(C) contrasting present circumstances with past circumstances
(D) questioning an assumption
(E) abstracting a general principle from specific data

I will go with B,
Gist of the Snippet:
Meteorite found. Options: Mars, Venus,Mercury >> Mercury eliminated with reason >> Venus eliminated with reason >> Therefore it came from Mars.
A- There is no "Counterexample"stated. C- Contrasting is done(for elimination of various possibilities) but not between Past and the Present events. D- The author never questions an assumption. He/She rather eliminates various possibilities using Facts. E- I didn't know what this option meant but I am guessing that it relates to "Creating something from a given data" which did not appeal to me
