Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 26.089% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(Cc2nc3ccc(C(=O)N(C)Cc4nccs4)cc3o2)cc1OC
b: COc1ccc(C(C[N+](=O)[O-])c2c(C)[nH]c3ccccc23)cc1OC
c: CN1CCN(c2nc3ccccc3nc2C(C#N)C(=O)OC2CCCCC2)CC1
Answer: b. COc1ccc(C(C[N+](=O)[O-])c2c(C)[nH]c3ccccc23)cc1OC
