Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.488\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCNC(=S)Nc1scc(-c2ccccc2)c1C(=O)OCC
b O=C(/C=C/c1ccccc1Cl)N(c1ccccn1)C1CCCCC1
c COc1ccc(-c2nc(CCNC(=O)c3ccco3)cs2)cc1OC
d O=C1/C(=C/Nc2ccc3c(c2)OCO3)CCc2ccccc21
e CC1CC(C)(C)NC(=S)N1CCC(=O)NCc1ccc(Cl)cc1
Answer: a. CCNC(=S)Nc1scc(-c2ccccc2)c1C(=O)OCC
