Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.465\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(CCN1C(=O)c2ccccc2C1=O)NNC(=O)c1ccc(Cl)cc1Cl
b CC(=O)c1ccccc1OC(=O)c1ccco1
c COc1ccc(-n2c(SCC(=O)Nc3sc4c(c3C#N)CCCC4)nnc2-c2ccc(O)cc2)cc1
Answer: b. CC(=O)c1ccccc1OC(=O)c1ccco1
