Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 18.955\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) CCOc1ccc(N2CC(O)=C(c3nc4ccccc4c(=O)[nH]3)C2=N)cc1
b) O=C1[C@@H]2Cc3c([nH]c4ccccc34)C(c3ccc(Cl)cc3)N2C(=O)CN1CCO
Answer: b. O=C1[C@@H]2Cc3c([nH]c4ccccc34)C(c3ccc(Cl)cc3)N2C(=O)CN1CCO
