Task: Answer the multiple choice question.
Question: Which drug has a 8.511\% 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) COc1cccc(-c2cc(C(=O)Nc3c(C)nn(Cc4ccccc4)c3C)no2)c1
(b) CCOC(=O)C1CCN(C(=O)/C=C/c2ccccc2)CC1
(c) CC(=O)Nc1ccc(NC(=O)CN(C)CCC#N)cc1
(d) Cc1ccc(C2CC(=O)NC(SCC(=O)Nc3nccs3)=C2C#N)cc1
Answer: b. CCOC(=O)C1CCN(C(=O)/C=C/c2ccccc2)CC1
