Task: Answer the multiple-choice question.
Question: Which drug has a 3.716\% 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, or c without using any other words.
Options:
(a) COc1ccc(CNc2ncc(-c3cccc([N+](=O)[O-])c3)n2C)c(OC)c1OC.O=C(O)C(=O)O
(b) O=C(COC(=O)c1ccccc1Br)NCCN1C(=O)CSC1=O
(c) CCOC(=O)CNC(=O)c1ccc(C#CC2(O)CCCCC2)cc1
Answer: b. O=C(COC(=O)c1ccccc1Br)NCCN1C(=O)CSC1=O
