Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.943\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COC(=O)C1=C(c2ccc(OC)c(OC)c2)C[C@@H]2CC[C@H]1N2C(=O)N1CCCCC1
b: O=C(NC1CCCC1)C(c1ccncc1)N(C(=O)c1ccco1)c1ccc(F)c(Cl)c1
Answer: b. O=C(NC1CCCC1)C(c1ccncc1)N(C(=O)c1ccco1)c1ccc(F)c(Cl)c1
