Problem statement: Answer the multiple choice question.
Question: Which drug has a 1.950\% 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 or b without using any additional words.
Options:
a) Cc1nn(CC(=O)Nc2cc(S(=O)(=O)N(C)C)ccc2Cl)c(C)c1[N+](=O)[O-]
b) Cc1cc(Oc2ncccc2[N+](=O)[O-])c2cc(Cl)ccc2n1
Answer: b. Cc1cc(Oc2ncccc2[N+](=O)[O-])c2cc(Cl)ccc2n1
