Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.428\% 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. CC(=O)c1ccc(S(=O)(=O)N2CCN(CC#N)CC2)cc1
b. O=C1C=C(/C=C/C2C=CC=CC2)C[C@@H](c2ccc(Cl)cc2)C1
c. O=C(CNC(=O)c1cccs1)N/N=C/c1cccc(Cl)c1
Answer: c. O=C(CNC(=O)c1cccs1)N/N=C/c1cccc(Cl)c1
