Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.935\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1ccc(CNC(=O)OCCN2CCN(Cc3ccccc3)CCC2=O)cc1
b: O=C1Nc2ccccc2Oc2cc([N+](=O)[O-])cc(Oc3ccccc3)c21
c: CCOc1ccc(OCC)c2sc(C)nc12
d: O=C(c1ccco1)N1CCC(c2nc(-c3ccccc3Cl)no2)CC1
e: COc1ccc(CC(C)NCCC(c2ccccc2)c2ccccc2)cc1
Answer: b. O=C1Nc2ccccc2Oc2cc([N+](=O)[O-])cc(Oc3ccccc3)c21
