Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.630\% 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: CCN1CCN(C(=O)C2COc3ccccc3O2)CC1
b: O=C(Nc1nnc(-c2ccccc2F)s1)c1cccnc1
c: COC(=O)Oc1ccc(/C=N/NC(=O)CN(c2ccccc2Br)S(C)(=O)=O)cc1OC
Answer: a. CCN1CCN(C(=O)C2COc3ccccc3O2)CC1
