Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.111\% human ether-à-go-go related gene (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[n+](CC(=O)Nc2cccc(Cl)c2)c1.[Cl-]
(b) CN(Cc1ccccc1)C(=O)c1[nH]cnc1C(=O)N[C@@H](Cc1ccccc1)C(=O)OCc1ccccc1
(c) CCOC(=O)C1=C(CC)OC(N)=C(C#N)C1c1ccc(OC)c(OC)c1OC
(d) CC(C)c1nc2c(c(=O)c3ccccc3n2C)c(=O)n1-c1ccc(F)cc1
Answer: d. CC(C)c1nc2c(c(=O)c3ccccc3n2C)c(=O)n1-c1ccc(F)cc1
