Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.543\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a NNC(=S)Nc1ccccc1Cl
b CCOC(=O)N1CCN(C(=O)c2ccc3c(=O)n(Cc4ccccc4OC)c(=S)[nH]c3c2)CC1
c NC(=O)C(=O)NN=C1CCC(c2ccccc2)CC1
Answer: b. CCOC(=O)N1CCN(C(=O)c2ccc3c(=O)n(Cc4ccccc4OC)c(=S)[nH]c3c2)CC1
