Task: Answer the MCQ question.
Query: Which compound exhibits a 18.764\% 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: CCC(=NCCc1ccccc1)c1c(O)[nH]c(=O)[nH]c1=O
b: CN(C)/C=N/C1=C(C#N)C(c2ccc(Br)cc2)c2ccc3ccccc3c2O1
c: N=C1C(c2nc3ccccc3s2)=C(O)CN1NC(=O)c1ccco1
Answer: b. CN(C)/C=N/C1=C(C#N)C(c2ccc(Br)cc2)c2ccc3ccccc3c2O1
