Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.500\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCOC(=O)Cc1csc(SCn2nnc3ccccc3c2=O)n1
[b] CN(C)CCNCCCOc1ccccc1-c1ccccc1.O=C(O)C(=O)O
[c] CCn1ncc(NC(=S)NCCc2ccc(OC)c(OC)c2)c1C(N)=O
Answer: b. CN(C)CCNCCCOc1ccccc1-c1ccccc1.O=C(O)C(=O)O
