Task: Answer the multiple choice question.
Query: Which drug exhibits a -5.072% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C(CSc1nc2ccccc2c(=O)[nH]1)NCc1ccc(Cl)cc1
b. COCCCNC(=O)/C(C#N)=C/c1cc(C)[nH]c1C
c. COc1ccc(OC)c(/C=C/C(=O)OCC(=O)Nc2nnc(-c3ccccc3)o2)c1
Answer: b. COCCCNC(=O)/C(C#N)=C/c1cc(C)[nH]c1C
