Task: Answer the multiple choice question.
Query: Which drug has a 4.300\% 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) COC(=O)c1cc(C(=O)c2cc(Cl)ccc2O)coc1=N
b) OCCN1CCN(C(=S)c2ccc(Cl)cc2)CC1
Answer: a. COC(=O)c1cc(C(=O)c2cc(Cl)ccc2O)coc1=N
