Task: Answer the multiple choice question.
Question: Which compound has a 3.185\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: Cc1ccc(CCNC(=O)CCNS(=O)(=O)c2ccc3c(c2)c(=O)n(C)c(=O)n3C)cc1
b: CSC1=NCCN1C(=O)c1cccc(Br)c1
c: CNC1=C([N+](=O)[O-])CC([N+](=O)[O-])=C(N2CCN(C(=O)Nc3ccc(Cl)cc3)CC2)N1C
d: CN1CCN(C(=O)c2cccc(COc3cc(Cl)ccc3Cl)c2)CC1
e: CCCN1Cc2cccc(C(=O)Nc3ccc4c(c3)OCCO4)c2C1=O
Answer: c. CNC1=C([N+](=O)[O-])CC([N+](=O)[O-])=C(N2CCN(C(=O)Nc3ccc(Cl)cc3)CC2)N1C
