Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.901\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COC(=O)c1c(NC(=O)COC(=O)CC(NC(C)=O)c2ccccc2)sc(C)c1C
b COc1ccc(S(=O)(=O)NCc2nc3nc(C)cc(C)n3n2)cc1OC
c c1ccc(OCc2nnnn2-c2ccccc2)cc1
d O=C(O)c1ccc2c(=O)n3c(nc2c1)/C(=C/c1ccc(C(F)(F)F)cc1)CC3
Answer: c. c1ccc(OCc2nnnn2-c2ccccc2)cc1
