Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 5.115\% 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] O=C(CN(c1cccc(Br)c1)S(=O)(=O)c1ccccc1)N/N=C/c1cc([N+](=O)[O-])ccc1O
[b] O=C(c1cccs1)N(C(=O)c1cccs1)c1ccccn1
[c] Cc1cccnc1NC(=O)c1cccc(NC(=O)CC2SC(N3CCCCC3)=NC2=O)c1
Answer: a. O=C(CN(c1cccc(Br)c1)S(=O)(=O)c1ccccc1)N/N=C/c1cc([N+](=O)[O-])ccc1O
