Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.328\% human ether-à-go-go related gene (hERG) inhibition at 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(COC(=O)c1c(F)cccc1F)Nc1ccc2[nH]c(=O)[nH]c2c1
[b] CCOC(=O)Cc1csc(NS(=O)(=O)c2cccc([N+](=O)[O-])c2)n1
[c] CCn1cc(C(C)NC(=O)COc2ccc(Cl)cc2C)c(C)n1
[d] O=[N+]([O-])c1ccccc1/C=N/n1c(-c2ccccc2)n[nH]c1=S
Answer: a. O=C(COC(=O)c1c(F)cccc1F)Nc1ccc2[nH]c(=O)[nH]c2c1
