Problem statement: Answer the multiple-choice question.
Query: Which drug has a 21.909% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CCc1cccc(NC(=S)N/N=C/c2cn(C)c3ccc(S(=O)(=O)N4CCOCC4)cc23)c1
b. O=C1ON=C(c2cccc([N+](=O)[O-])c2)/C1=C/c1ccc(O)cc1
Answer: b. O=C1ON=C(c2cccc([N+](=O)[O-])c2)/C1=C/c1ccc(O)cc1
