Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.873\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. CC1(C)Cc2ccccc2-c2c1c(=O)n(Cc1ccccc1)c1nnnn21
b. Cc1ccc(NC(=O)CNc2ccc(OC(C)C)cc2)cc1
c. CCOC(=O)c1c(S(=O)(=O)N2CCN(C)CC2)c(C)n(C)c1C
d. COc1ccccc1CCc1nnc(CCC(=O)NCC2CCCO2)o1
e. CN1C(=O)c2ccc(NC(=O)CSc3ccccc3)cc2C1=O
Answer: c. CCOC(=O)c1c(S(=O)(=O)N2CCN(C)CC2)c(C)n(C)c1C
