Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -0.078\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C1CCCN1CCCNC(=S)Nc1ccc(Cl)cc1Cl
b: O=C1/C(=C/Nc2ccc3c(c2)OCO3)CCc2ccccc21
c: CCOC(=O)CSC1=C(C#N)C(c2ccccc2C)C2=C(CCCC2=O)N1
Answer: a. O=C1CCCN1CCCNC(=S)Nc1ccc(Cl)cc1Cl
