Task: Answer the multiple choice question.
Question: Which drug has a -4.329\% 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, c, or d without using any other words.
Options:
a: COC(=O)CNC(=O)C(C)NC(=O)CNC(=O)OCc1ccccc1
b: COc1ccc(CNC(=O)CN(c2cccc(OC)c2)S(C)(=O)=O)cc1
c: CCOC(=O)Cc1nnc(NC(=O)COc2ccc(OC)cc2)s1
d: CCc1cc(Br)ccc1NC(=O)C1CCCO1
Answer: c. CCOC(=O)Cc1nnc(NC(=O)COc2ccc(OC)cc2)s1
