Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 19.582% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C1C2C3c4ccccc4C(c4ccccc43)C2C(=O)N1c1nc(-c2ccccc2)cs1
b. CCN(CC)S(=O)(=O)c1cc(OC)c(C)cc1C
c. N#CC1=C(N)C2=CCCC[C@H]2[C@H](c2cccc(F)c2)C1(C#N)C#N
d. O=C(Nc1ccc([N+](=O)[O-])cc1)Nc1ccc(OC(F)F)c(Cl)c1
Answer: d. O=C(Nc1ccc([N+](=O)[O-])cc1)Nc1ccc(OC(F)F)c(Cl)c1
