Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.861\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C1c2ccccc2C(=O)N1CCOc1ccc(F)cc1
[b] CCOc1ccc(N2C(=O)C3ON(C)C(c4ccc([N+](=O)[O-])cc4)C3C2=O)cc1
[c] O=C(NNC(=O)C1CC1)c1ccc(-c2ccccc2)cc1
[d] CC1(C)Cc2c(C#N)c(NCCc3ccccc3)nc(-c3ccco3)c2CO1
Answer: c. O=C(NNC(=O)C1CC1)c1ccc(-c2ccccc2)cc1
