Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.394\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(COC(=O)c1ccc(O)cc1O)c1ccc(Cl)cc1
b O=C(NCCN1CCN(Cc2ccccc2)CC1)C1CC(=O)N(C2CCCC2)C1
c Sc1oc(-c2ccccc2)cc1C=Nc1ccccc1
Answer: b. O=C(NCCN1CCN(Cc2ccccc2)CC1)C1CC(=O)N(C2CCCC2)C1
