Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.829\% 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) O=C(N/N=C/c1cc(Cl)cc([N+](=O)[O-])c1O)C1CC1
b) O=C(N/N=C/c1cccc(O)c1)c1csc2ccccc12
Answer: a. O=C(N/N=C/c1cc(Cl)cc([N+](=O)[O-])c1O)C1CC1
