Task: Answer the multiple-choice question.
Question: Which drug has a 11.300\% 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: Cc1cccc(NC(=O)c2ccc3c(=O)n4c(nc3c2)CCCCC4)n1
b: O=C(Cc1ccccc1[N+](=O)[O-])NCCc1ccc(F)cc1
c: CCC(C(=O)Nc1nc(C)c(C)s1)c1ccccc1
d: O=C1/C(=C/c2ccc3c(c2)OCO3)Oc2cc(OCC(=O)N3CC(O)C[C@H]3C(=O)O)ccc21
Answer: b. O=C(Cc1ccccc1[N+](=O)[O-])NCCc1ccc(F)cc1
