Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.870\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccc(Cl)cc1S(=O)(=O)Oc1ccc(NC(C)=O)cc1
b: CCn1c(COc2ccccc2C)nc2ccccc21
c: Cc1nc(CC(=O)NNS(=O)(=O)c2ccc(F)c(Cl)c2)cs1
Answer: b. CCn1c(COc2ccccc2C)nc2ccccc21
