Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.436\% 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 other words.
Options:
a) CCOc1ccc(S(=O)(=O)NCCC(=O)NCc2cccnc2)cc1
b) CC(C)(C)OC(=O)N[C@@H](CC(=O)OCc1ccccc1)C(=O)O
c) CC1CN(c2ccc([N+](=O)[O-])cc2C(=O)N2CCOCC2)CC(C)N1
d) CCN(CC)S(=O)(=O)c1ccc(OC(C)C)c(NC(=O)C2=COCCO2)c1
e) CC1CN(S(=O)(=O)c2cccc(C(F)(F)F)c2)CN1C(=O)N1CCOCC1
Answer: b. CC(C)(C)OC(=O)N[C@@H](CC(=O)OCc1ccccc1)C(=O)O
