Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.216\% 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: CCCCn1c(N)c(N(CCOC)C(=O)c2cc3c(s2)CCCCC3)c(=O)[nH]c1=O
b: COc1ccccc1C(=O)Nc1c2c(nn1-c1cccc(C)c1C)CS(=O)C2
c: O=C(O)c1cccc(NC(=O)c2ccc(CN3C(=O)c4ccccc4C3=O)cc2)c1
Answer: b. COc1ccccc1C(=O)Nc1c2c(nn1-c1cccc(C)c1C)CS(=O)C2
