Task: Answer the multiple choice question.
Question: Which drug exhibits a 25.420\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=[N+]([O-])c1ccc(-c2cn(-c3ccc(Cl)cc3)c(=S)[nH]2)cc1
(b) COc1ccc(NS(=O)(=O)c2cc(NC(=O)c3cnc(C)cn3)ccc2N2CCCC2)cc1
(c) Cc1nnc2sc(SCC(=O)Nc3nccs3)nn2c1=O
(d) COc1ccccc1C(=O)Nc1ccc(C(=O)N2CCCCC2)cc1
Answer: c. Cc1nnc2sc(SCC(=O)Nc3nccs3)nn2c1=O
