Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 8.606% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCOC(=O)c1sc(-c2ccc(C)cc2)c(C#N)c1C
(b) COc1cccc(-c2nc(SCC(=O)Nc3nc(-c4ccccc4)c(C)s3)[nH]c(=O)c2C#N)c1
(c) O=C(c1cnn2ccccc12)N1CCCc2ccccc21
(d) O=C(O)c1cn(CCOc2ccccc2Cl)c2ccccc12
Answer: a. CCOC(=O)c1sc(-c2ccc(C)cc2)c(C#N)c1C
