Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.763\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:

[b] Cc1ccc(NC(=O)CSc2nc3c(c(=O)n(C)c(=O)n3C)n2C)cc1
[c] CONC(=O)Nc1ccccc1[N+](=O)[O-]
[d] COc1ccc(-c2nnc(SCC(=O)N3CCC(Cc4ccccc4)CC3)o2)cc1OC
Answer: c. CONC(=O)Nc1ccccc1[N+](=O)[O-]
