Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 8.366\% 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: O=C(COC(=O)c1cncc(Br)c1)Nc1ccc2c(c1)OCO2
b: CCN(CC)c1ccc(-c2sc(Nc3ccccc3)n[n+]2-c2ccc(F)cc2)cc1.[Cl-]
c: O=[N+]([O-])c1cccc(-c2c(-c3ccccc3)ncc3cc(F)ccc23)c1
d: CC1Sc2ccc(S(=O)(=O)CCC(=O)N3CCCC3)cc2NC1=O
Answer: c. O=[N+]([O-])c1cccc(-c2c(-c3ccccc3)ncc3cc(F)ccc23)c1
