Task: Answer the multiple-choice question.
Query: Which drug has a -31.555\% 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: O=C(c1cccc(F)c1)N1CCN(c2ccc([N+](=O)[O-])c3cccnc23)CC1
b: CCCCN(CC)S(=O)(=O)N1CCC(C(=O)NCc2ccc(F)cc2)CC1
Answer: a. O=C(c1cccc(F)c1)N1CCN(c2ccc([N+](=O)[O-])c3cccnc23)CC1
