Task: Answer the multiple choice question.
Question: Which drug has a -0.492\% 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(C[n+]1ccccc1)N/N=C/c1ccccc1Cl.[Cl-]
b. CS(=O)(=O)N(CC(=O)NCc1ccccc1)c1ccc(Cl)cc1
c. O=C(Nc1cccc(NC(=O)c2cccs2)c1)c1ccc2c(c1)OCO2
Answer: c. O=C(Nc1cccc(NC(=O)c2cccs2)c1)c1ccc2c(c1)OCO2
