Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -3.210% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(CNS(=O)(=O)c1c(F)cc(F)cc1Br)OCC(=O)N1CCCC1=O
b: COc1ccc(COc2cc(-c3cccc(OC)c3)nc3ccc(NC(=O)c4ccc(N(C)C)cc4)cc23)cc1
c: CC1CCCN(C/C=C/c2ccccc2[N+](=O)[O-])C1
d: NC(=O)CC(NC(=O)Cc1cccc2ccccc12)c1ccc(NCc2ccccn2)c([N+](=O)[O-])c1
Answer: a. O=C(CNS(=O)(=O)c1c(F)cc(F)cc1Br)OCC(=O)N1CCCC1=O
