Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 27.696% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCc1c(C)nc(SCC(=O)NC2CCCC2)[nH]c1=O
b: Cc1ccccc1N1CCN(C2CCCN(C(=O)COc3ccccc3)C2)CC1
c: COc1ccccc1CNC(=O)COc1cccnc1[N+](=O)[O-]
d: O=C(NCc1ccco1)c1scc2c1OCCO2
Answer: a. CCc1c(C)nc(SCC(=O)NC2CCCC2)[nH]c1=O
