Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.439\% 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 other words.
Options:
a: Cc1ccc(C)c(NC(=O)C(OC(=O)c2cnc(C)cn2)c2ccccc2)c1
b: O=C(O)C1CN(c2ncccc2[N+](=O)[O-])C1
c: C/C(CCc1ccccc1)=N/NC(=O)C(=O)NCc1ccccc1
d: COc1ccc(-n2cnc3c(cnn3CCC#N)c2=N)cc1
Answer: b. O=C(O)C1CN(c2ncccc2[N+](=O)[O-])C1
