Task: Answer the multiple-choice question.
Query: Which drug exhibits a 21.236\% 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 other words.
Options:
a: COC(=O)[C@H](CCSC)NC(=O)Nc1cc(C)ccc1C
b: Nc1nc(N)nc(-c2cccc(Cl)c2Cl)n1
c: Cc1cc(NC(=O)CSCC(=O)OCC(=O)Nc2cc(C)c(C)cc2[N+](=O)[O-])no1
Answer: b. Nc1nc(N)nc(-c2cccc(Cl)c2Cl)n1
