Saundarya’s Skin Nourishing cream sold 5 lakh packs last quarter, 20% more than their Face Wash did and nearly five times as much as their Anti-Ageing cream sales.

Option C is the correct answer.

In this phrasing, "their Face Wash" correctly compares sales without unnecessary repetition of "did" or "sold."

Additionally, since the statement uses "more" in the former part of the sentence, the latter part should also use "more" to maintain parallelism. The use of "as much as" is incorrect. 

Option A is redundant and awkward.
Option B has incorrect parallelism. 
Option D has awkward phrasing.
