Task: Answer the multiple choice question.
Query: Which drug has a 17.284\% 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 other words.
Options:
(a) O=C(CN1CCN(Cc2ccccc2)CC1)NCCc1ccccc1
(b) COc1cccc(N(C(C)=O)C2=NCCCS2)c1
Answer: b. COc1cccc(N(C(C)=O)C2=NCCCS2)c1
