Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.673\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CC(=O)Oc1ccc(N2C(=O)C3C(C2=O)C2(C)C=CC3(C)O2)cc1
(b) O=C(NNC1CC(=O)N(c2ccc(Br)cc2)C1=O)c1cccs1
Answer: b. O=C(NNC1CC(=O)N(c2ccc(Br)cc2)C1=O)c1cccs1
