Task: Answer the multiple choice question.
Query: Which drug has a 3.976\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cc1ccc(C(=O)N2CCN(c3ccccc3)CC2)cc1S(=O)(=O)N1CCCC1
b: O=C(/C=C/c1ccc(Cl)cc1Cl)NCCN1CCOCC1
Answer: a. Cc1ccc(C(=O)N2CCN(c3ccccc3)CC2)cc1S(=O)(=O)N1CCCC1
