Problem statement: Answer the multiple choice question.
Question: Which drug has a 20.540\% 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) COc1ccc(Cc2nnc(NC(=O)c3ccc(OC(C)=O)cc3)s2)cc1OC
b) O=C(Nc1cc(Cl)ccc1Cl)C1CC(=O)N(c2ccc(Br)cc2)C1
Answer: b. O=C(Nc1cc(Cl)ccc1Cl)C1CC(=O)N(c2ccc(Br)cc2)C1
