Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.780\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(Nc1ccc2oc(=O)ccc2c1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
b: O=[N+]([O-])c1cc([N+](=O)[O-])c(Oc2c(F)ccc(F)c2F)cc1NN1CCCCC1
c: CCOc1cc(/C=C2\SC(=S)N(NS(=O)(=O)c3ccccc3)C2=O)ccc1O
d: CCOc1ccccc1CN(CCc1ccc2c(c1)OCO2)Cc1ccccn1
Answer: b. O=[N+]([O-])c1cc([N+](=O)[O-])c(Oc2c(F)ccc(F)c2F)cc1NN1CCCCC1
