Task: Answer the multiple choice question.
Question: Which drug has a -7.539\% 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(c1ccc(Oc2ccc(C(F)(F)F)cc2[N+](=O)[O-])cc1)N1CCOCC1
[b] O=C(COC(=O)CCCSc1nc2ccccc2[nH]1)Nc1cccc2ccccc12
[c] COc1ccccc1C(=O)COC(=O)COc1cccc2c1OC(C)(C)C2
Answer: a. O=C(c1ccc(Oc2ccc(C(F)(F)F)cc2[N+](=O)[O-])cc1)N1CCOCC1
