Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -1.682% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOC(=O)CSc1nnc(NC(=O)c2cccc([N+](=O)[O-])c2)s1
b: CC(=O)c1ccc(NC(=O)Oc2ccccc2)cc1
c: C=CCn1c(NC(=O)CC)c(C(=O)OCC)sc1=S
d: COC(=O)C1=C(c2cccc(OCc3ccccc3)c2)C[C@@H]2CC[C@H]1N2C(=O)NCc1cccc(F)c1
Answer: a. CCOC(=O)CSc1nnc(NC(=O)c2cccc([N+](=O)[O-])c2)s1
