Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.898\% 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: CCOC(=O)c1c(C)nc2sc(C(N)=O)c(N)c2c1-c1ccc(OC)cc1
b: COc1ccc(NC(=O)C2CCCN(S(=O)(=O)c3cnc[nH]3)C2)cc1
c: CCOCCC(=O)Nc1cc(Cl)ccc1OC
Answer: c. CCOCCC(=O)Nc1cc(Cl)ccc1OC
