Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.568% 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 CCCNc1nc(C)c(C(C)=O)cc1C#N
b Cc1nn(C)cc1C(=O)N(C)C12CC3CC(CC(C3)C1)C2
c COC(=O)CCCC1=CC2=CC(=O)C(C)(OC(=O)c3cccs3)C(=O)C2=CN1Cc1ccco1
d O=C(c1cc2ccccc2cc1O)N1CCCC1
Answer: a. CCCNc1nc(C)c(C(C)=O)cc1C#N
