Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 8.517\% 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. COc1ccc(CN2CCNC(=O)C2CC(=O)NCCCn2nnc3ccccc32)cc1C
b. CO/C(N)=C(\C#N)N=Cc1ccccc1Cl
c. CCOC(=O)c1sc(S(C)=O)c2c1CCc1conc1-2
Answer: b. CO/C(N)=C(\C#N)N=Cc1ccccc1Cl
