Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.141\% 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=C1NC(=O)C2(Cc3ccccc3N3CCOCC32)C(=O)N1c1ccccc1
b. CCN(c1ccc(OC)cc1)S(=O)(=O)c1ccc2c(c1)CC(C)N2C(=O)C1CC1
c. O=C(Nc1c2c(nn1-c1cccc(Cl)c1)CS(=O)(=O)C2)c1cccs1
Answer: c. O=C(Nc1c2c(nn1-c1cccc(Cl)c1)CS(=O)(=O)C2)c1cccs1
