Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.530\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Cn1c(COc2ccccc2)nnc1SCC(=O)Nc1ccc(N2CCOCC2)cc1
b: C=CCN(c1ccccc1)S(=O)(=O)c1cc2c(cc1C)N(C)CCO2
c: Cc1cc(NS(=O)(=O)c2ccc(NC(=O)COc3ccccc3[N+](=O)[O-])cc2)no1
Answer: b. C=CCN(c1ccccc1)S(=O)(=O)c1cc2c(cc1C)N(C)CCO2
