Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.575\% 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] CN(CC(=O)Nc1ccccc1F)CC(=O)Nc1ccccc1Br
[b] O=[N+]([O-])c1cc(Cl)ccc1NCCNS(=O)(=O)c1ccccc1
[c] CC(=O)Nc1ccccc1-c1nn2c(C)csc2nc1=O
[d] CCOC(=O)c1c(NC(=O)CSc2nncs2)sc(C)c1C
Answer: c. CC(=O)Nc1ccccc1-c1nn2c(C)csc2nc1=O
