Task: Answer the multiple choice question.
Question: Which compound has a 18.836\% 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 Cc1c(NC(=O)CSc2nnc3sc4ccccc4n23)c(=O)n(-c2ccccc2)n1C
b O=C(CNC(=O)c1ccc(Br)cc1)NCC(=O)OCc1ccc(Cl)cc1
c COc1ccccc1CNC(=O)c1[nH]c(C)c(C(C)=O)c1C
Answer: c. COc1ccccc1CNC(=O)c1[nH]c(C)c(C(C)=O)c1C
