Task: Answer the multiple choice question.
Question: Which drug exhibits a -3.369% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. COc1cccc2c1OCC(CN1CCN(CCC(C)C)C(CCO)C1)=C2
b. O=C(COc1ccc(Cl)cc1Cl)Nc1c(-c2cccs2)nc2ccccn12
c. O=C(NCCC1=CCCCC1)C(=O)NCC(c1ccco1)N1CCN(c2ccc(F)cc2)CC1
d. Oc1ccc(Oc2ncc(Cl)cc2Cl)cc1
e. COc1cc(/C=C2/OC(=O)c3cc([N+](=O)[O-])ccc32)cc(OC)c1OC
Answer: a. COc1cccc2c1OCC(CN1CCN(CCC(C)C)C(CCO)C1)=C2
