Task: Answer the multiple-choice question.
Query: Which drug exhibits a -77.524% human ether-à-go-go related gene (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) O=C(Cc1ccccc1)N/N=C/c1ccc2cccc(O)c2n1
b) CCOc1ccc(N2C(=O)CC(NCCNc3ccc([N+](=O)[O-])cn3)C2=O)cc1
c) O=C(Nc1ccc(C(=O)O)cc1)/C(=C/c1cccc(Br)c1)NC(=O)c1ccco1
Answer: b. CCOc1ccc(N2C(=O)CC(NCCNc3ccc([N+](=O)[O-])cn3)C2=O)cc1
