Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.051\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=S(=O)(c1cccs1)N1CN(Cc2ccco2)c2nc3ccccc3nc21
b) CN1CCOc2cc(S(=O)(=O)NCc3ccc(S(N)(=O)=O)cc3)ccc21
c) O=C(c1ccccc1)c1ccc(-n2cnnc2)c([N+](=O)[O-])c1
Answer: a. O=S(=O)(c1cccs1)N1CN(Cc2ccco2)c2nc3ccccc3nc21
