Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.886% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COC(=O)c1ccc(N2CCN(c3ccccc3)CC2)c(NC(=O)C2CC2)c1
[b] Cc1cccc(-c2c3c(=O)n(C)c(=O)n(C)c3c3cccnn23)c1
[c] CC(C)(C)C(=O)/C=c1\s/c(=C\c2ccc(-c3ccc([N+](=O)[O-])cc3)o2)c(=O)n1CC(=O)NC(N)=O
Answer: c. CC(C)(C)C(=O)/C=c1\s/c(=C\c2ccc(-c3ccc([N+](=O)[O-])cc3)o2)c(=O)n1CC(=O)NC(N)=O
