Task: Answer the multiple-choice question.
Query: Which compound exhibits a 9.429\% 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. O=C(c1ccccc1)N1CCN2C(=O)c3ccccc3C12c1ccc(Cl)cc1
b. O=C1NC(Nc2ccccn2)(C(F)(F)F)C(=O)N1c1ccc(F)cc1
c. CN(CCOc1ccc(NS(C)(=O)=O)cc1)CCc1ccc(NS(C)(=O)=O)cc1
d. C=CCn1cnc2c(oc3ccccc32)c1=O
e. CCN1CCCC1CNC(=O)c1ccc2c(c1)NC(=O)/C(=C\c1ccc(OC)c(OC)c1)S2
Answer: b. O=C1NC(Nc2ccccn2)(C(F)(F)F)C(=O)N1c1ccc(F)cc1
