Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -16.721% 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 other words.
Options:
a: C=CCNC(=O)c1ccc(C)cc1Cl
b: O=C1OCc2cc(NC(=O)C3CCCCC3)ccc21
c: c1ccc(-c2nnc(-c3ccccn3)s2)nc1
d: CCn1c(SCC(=O)NC(C)(C)C)nnc1-c1ccoc1C
e: COc1cc(/C=N/O)ccc1OCc1ccc([N+](=O)[O-])cc1
Answer: a. C=CCNC(=O)c1ccc(C)cc1Cl
