Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -25.003\% 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(C1CCC(=O)N(C2CCCC2)C1)N1CCC(Oc2ccccc2Cl)CC1
b: Cc1nc(C)c(CC(=O)N/N=C/c2ccc(O)cc2)c(=O)[nH]1
Answer: a. O=C(C1CCC(=O)N(C2CCCC2)C1)N1CCC(Oc2ccccc2Cl)CC1
