Task: Answer the MCQ question.
Question: Which drug exhibits a -0.818\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(NCCNc1ccc([N+](=O)[O-])cc1C(F)(F)F)c1cccc(F)c1
b) CC(C)c1ccc(/C=C/C(=O)NCc2ccc(S(N)(=O)=O)cc2)cc1
c) Cc1ccc(NC(=O)c2c(F)cccc2Cl)cc1S(=O)(=O)N1CCOCC1
Answer: a. O=C(NCCNc1ccc([N+](=O)[O-])cc1C(F)(F)F)c1cccc(F)c1
