Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.341\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1cc(C2CC(=O)N(CC(=O)NCC3CCCO3)c3ccccc3S2)cc(OC)c1OC
b. Cc1oc(-c2ccccc2F)nc1CS(=O)CC(=O)NC1CCCC1
c. CCOc1ccc2nc(COC(=O)c3cccc([N+](=O)[O-])c3)c(C(C)=O)[n+]([O-])c2c1
d. N=C1C(c2ccccc2)=C(O)CN1c1cccc(S(=O)(=O)Nc2cccc(C(F)(F)F)c2)c1
Answer: c. CCOc1ccc2nc(COC(=O)c3cccc([N+](=O)[O-])c3)c(C(C)=O)[n+]([O-])c2c1
