Task: Answer the multiple choice question.
Question: Which drug has a 16.362\% 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: COc1ccc(N(CC(=O)N2CCOCC2)S(C)(=O)=O)cc1
b: O=c1ccnc(Nc2ccc(Cl)cc2)[nH]1
c: Cc1ccc(CNC(=O)c2ccc(N3CCC4(CC3)CC(c3ccccc3)=NO4)c(NC(=O)c3ccc(Br)cc3)c2)cc1
d: COc1ccc(NC(=O)NCc2cccnc2)c(OC)c1
e: CN(CC(=O)Nc1cccc(F)c1)C(=O)c1ccccc1OCC(=O)Nc1cccc(C(F)(F)F)c1
Answer: a. COc1ccc(N(CC(=O)N2CCOCC2)S(C)(=O)=O)cc1
