Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.315\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: C=CCNc1oc(COc2ccc(C)cc2)nc1C#N
b: O=C(c1ccc(Cl)c(Cl)c1)N1CCOCC1
c: COc1ccc([N+](=O)[O-])cc1NS(=O)(=O)c1ccccc1
d: Cc1cc(=O)[nH]c(SCC(=O)Nc2ccc(S(=O)(=O)N3CCCCC3)cc2)n1
Answer: a. C=CCNc1oc(COc2ccc(C)cc2)nc1C#N
