Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.100\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CN1CCN(C2=Nc3c(Cl)cc(Cl)c4cccc2c34)CC1
b Cc1ccc(SCCC(=O)N(C)C)cc1
c COc1cc(NC(=O)C23CC4CC(C2)CC(n2nnc(C)n2)(C4)C3)c(OC)cc1Cl
Answer: b. Cc1ccc(SCCC(=O)N(C)C)cc1
