Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.635% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. Nc1cc2c(cc1[N+](=O)[O-])OCCO2
b. COc1ccc(CCNC(=O)COc2ccc(S(=O)(=O)NC(C)C)cc2)cc1OC
c. CCCCNC(=O)c1cn(CC)c2ccc(S(=O)(=O)N3CCCCCC3)cc2c1=O
Answer: a. Nc1cc2c(cc1[N+](=O)[O-])OCCO2
