Task: Answer the multiple-choice question.
Question: Which drug exhibits a 14.579\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: C=C1CCN(c2ccc(C(=O)NCc3ccccc3)cc2[N+](=O)[O-])CC1
b: CCOC(=O)C1=C(C)NC(=O)CC1c1cc2c(cc1[N+](=O)[O-])OCO2
c: O=C(NCCc1ccccn1)c1ccc(OC2CCN(Cc3ccccn3)CC2)cc1
Answer: b. CCOC(=O)C1=C(C)NC(=O)CC1c1cc2c(cc1[N+](=O)[O-])OCO2
