Task: Answer the multiple choice question.
Query: Which drug exhibits a 10.486% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCCCN1C(=O)C(NC(C)=O)c2cc(Br)ccc21
[b] O=C(NC(=S)NN1CCCCC1c1cccnc1)c1ccc(Cl)cc1Cl
[c] CCCCn1c(=S)[nH]c2ncccc2c1=O
Answer: c. CCCCn1c(=S)[nH]c2ncccc2c1=O
