Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.198\% 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(Nc1cccnc1Cl)c1cccc(F)c1
b COc1cccc(CNC(=O)C2=Cc3cccc(OC)c3OC2)c1
c CC/C(CC(=O)C(F)(F)F)=N\NC(=O)/C(C#N)=C/N(C)C
d O=C(O)Cc1sc(-c2ccccc2)nc1-c1ccccc1
Answer: a. O=C(Nc1cccnc1Cl)c1cccc(F)c1
