Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.884% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a NC(=O)c1cc2ccccc2o/c1=N/NC(=O)c1cccc(F)c1
b Cl.O=C(NCc1nc2ccccc2[nH]1)c1c(F)c(F)c(F)c(F)c1F
c CCc1ccc(NC(=O)C2CCN(S(=O)(=O)c3c(C)[nH]c(=O)[nH]c3=O)CC2)cc1
Answer: c. CCc1ccc(NC(=O)C2CCN(S(=O)(=O)c3c(C)[nH]c(=O)[nH]c3=O)CC2)cc1
