Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.476\% 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 other words.
Options:
a: O=C(O)Cc1coc2ccc3ccccc3c12
b: CCCC(=O)Nc1sc(C(=O)OC)c(C)c1C(N)=O
c: COc1ccccc1/C=C/C(=O)c1ccccc1
d: CC(C)CNC(=S)NC(=O)c1csc([N+](=O)[O-])c1
Answer: b. CCCC(=O)Nc1sc(C(=O)OC)c(C)c1C(N)=O
