Problem statement: Answer the multiple-choice question.
Query: Which drug has a 8.966\% 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: Cl.O=C(O)c1ccc2nc(CO)[nH]c2c1
b: Cc1ccc(S(=O)(=O)CCc2nnc(NC(=O)COc3cccc(C)c3)s2)cc1
Answer: a. Cl.O=C(O)c1ccc2nc(CO)[nH]c2c1
