Elements that can be identified
1. Usage of a pronoun which
2. comparison..- degree of catering of mercury vs degree of catering of moon.
3. 2 clauses - A comma after distances.

Option A
Which is a pronoun . Its antecedent is Distance. Did  distance  reveal anything.. No.. Option A is ruled out.

Option B
Degree of catering of mercury is compared to moon.. That comparison is absurd. The correct comparison is Degree of catering of mercury and degree of catering of moon. Option B has an error

Option C
Revealing is a participle. The participle phrase - Revealing.... is predicated of the main subject - large area of surface. The large area  was revealing information via a photograph. The sentence structure is precise and unambiguous.  The comparison is appropriate. "That of" indicates a feature of moo. The comparison here is between feature of mercury(Degree of cratering) and feature of moon.

Option C is correct.

Option D
And indicates. that large area revealed two features.  From the intended meaning, only one feature, degree of cratering, is mentioned. Also a comparison error. ( same as option B)  Hence Option D has a multiple errors.

Option E
Which noun does "that" refers to?  Large area or photograph ?? It is not clear.  Option E is elliminated

Hence option C is the correct answer.
