Task: Answer the multiple choice question.
Question: Which drug has a 19.476% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CN(CC(=O)Nc1ccccc1Br)C(=O)c1cccnc1Nc1cccc(C(F)(F)F)c1
[b] O=C(COC(=O)c1ccc([N+](=O)[O-])s1)NCc1ccc(F)cc1
[c] N/C(=N\OS(=O)(=O)c1ccc(Br)cc1)c1ccncc1
[d] COc1ccc(NC(=O)CN2C(=O)CSc3ccc(S(=O)(=O)N4CCCC4)cc32)cc1OC
Answer: b. O=C(COC(=O)c1ccc([N+](=O)[O-])s1)NCc1ccc(F)cc1
