Task: Answer the multiple choice question.
Question: Which compound exhibits a 22.991\% 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) CCO/C=C1\SC(=S)N(c2ccc(Cl)cc2)C1=O
(b) CCc1nnc(NC(=O)CCN2C(=O)c3ccccc3C2=O)s1
(c) COc1ccc(S(=O)(=O)N(C)C)cc1NCC(=O)Nc1cccc(C#N)c1
(d) CCCOc1ccc(NC(=O)CC2Nc3ccccc3NC2=O)cc1
Answer: a. CCO/C=C1\SC(=S)N(c2ccc(Cl)cc2)C1=O
