Task: Answer the multiple-choice question.
Question: Which drug has a 9.747\% 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 additional words.
Options:
a. O=C(O)c1cc(NN=Nc2ccc(Br)cc2)cc([N+](=O)[O-])c1
b. COc1cc2cnc(Cl)nc2cc1OC
c. c1ccc(-c2nc(NCc3ccco3)c3ccccc3n2)nc1
d. CS(=O)(=O)n1nc(-c2ccccc2)nc1N
Answer: a. O=C(O)c1cc(NN=Nc2ccc(Br)cc2)cc([N+](=O)[O-])c1
