Task: Answer the multiple choice question.
Question: Which compound exhibits a -16.150% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Fc1ccccc1CSc1nnc(-c2ccccc2)o1
b: CCOC(=O)c1cnc(Nc2nc3ccccc3o2)nc1C
c: N#CCCN(C(=O)COc1ccc(C#N)cc1)c1ccc(F)cc1
d: O=C(COC(=O)C1CCCCC1)Nc1ccc([N+](=O)[O-])cc1
Answer: b. CCOC(=O)c1cnc(Nc2nc3ccccc3o2)nc1C
