Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.995\% 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 CCN(CC)S(=O)(=O)c1ccc(Cl)c(C(=O)NC)c1
b O=C(O)c1nn(-c2ccc(Cl)cc2)ccc1=O
Answer: b. O=C(O)c1nn(-c2ccc(Cl)cc2)ccc1=O
