A detailed lab analysis of a meteorite recently discovered

A detailed lab analysis of a meteorite recently discovered in Antarctica revealed that the meteorite has geological characteristics common to the planet Mars. To date, scientists have not found these characteristics anywhere other than on Mars.using a technique called "acid-etching" scientist found that the meteorite contained fossilized remains of single-cell life forms.

The statement above, if true, best support which of the following as a conclusion?

a) The fossilized remains indicate that life exists on Mars
The remains of single-cell life forms were found. That doesn't substantiate the idea that life currently exists on Mars. We find dinosaur fossils here on Earth, but no dinosaurs exist today.
b)The scientists have evidence to support a hypothesis that the meteorite came from mars.
The geological characteristics found in the meteorite are common to the geology of Mars. Scientist have only found these characteristics on Mars, so this is enough evidence to support the hypothesis.
c) The meteorite represents a substantial step forward in human knowledge of the development of life in the solar system.Totally out of the scope of the argument.
d) undiscovered meteorites currently exist in Antarctica
They could exist anywhere in the world.
e) "Acid - etching" is necessary to confirm the existence of fossilized remains in meteorites.
This is just one process that scientists use to further examine the meteorite. There could be many other processes that aren't mentioned.

B is the correct answer
