Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 18.882\% 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) CCCc1ccccc1OCCNC(C)=O
(b) CC(=O)/C(C#N)=C1\NC(=O)C(Cc2ccccc2)S1
(c) CCOC(=O)C(Cc1ccccc1)NC(=O)CCc1c(C)nc2nc(C)nn2c1C
(d) CCC(=O)Nc1cc(C(C)C)c(O)cc1C
Answer: b. CC(=O)/C(C#N)=C1\NC(=O)C(Cc2ccccc2)S1
