Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -16.960\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCN1CCN(C(CNS(=O)(=O)c2ccc(OC)cc2)c2cccnc2)CC1
(b) S=C(Nc1ccccc1)Nn1cnnc1
(c) O=C(C1=C[C@@H](c2ccccc2)C[C@@H](OCCCCO)O1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
(d) O=C(COC(=O)c1cccc(Cl)c1Cl)NCCN1C(=O)CSC1=O
Answer: a. CCN1CCN(C(CNS(=O)(=O)c2ccc(OC)cc2)c2cccnc2)CC1
