Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.202% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. CSc1ccc(S(=O)(=O)NCC(=O)OCC(=O)N(C)CC(=O)Nc2ccccc2Cl)cc1[N+](=O)[O-]
b. CCC(=O)N1CC23C=CC(CC2CC12CCCCC2)O3
c. COc1ccc(OCC(=O)N/N=C/c2ccc(OC)c(OC)c2C(=O)O)cc1
d. Cc1ccc(S(=O)(=O)NC(CC(C)C)C(=O)NCc2ccco2)cc1
e. Cc1nn(Cc2cccc(F)c2)c(C)c1NC(=O)c1c([N+](=O)[O-])c(C)nn1C
Answer: b. CCC(=O)N1CC23C=CC(CC2CC12CCCCC2)O3
