Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 9.302\% 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: O=C(NCc1ccccc1)c1ccc(Cl)cc1
b: CC(NC(=O)COC(=O)c1ccc2c(c1)S(=O)(=O)N=C1CCCCCN12)C12CC3CC(CC(C3)C1)C2
c: Cc1ccc(CC(CC(=O)O)C(=O)NC2CCCCC2)cc1
d: O=C(NCCNc1ccc([N+](=O)[O-])cc1)c1ccccc1F
Answer: d. O=C(NCCNc1ccc([N+](=O)[O-])cc1)c1ccccc1F
