Task: Answer the MCQ question.
Question: Which drug exhibits a -0.308\% 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: COc1ccc(Cl)cc1CN1C(=O)NC2(CCCCCC2)C1=O
b: CN(C)c1ccc(/C=N/n2c(COc3ccccc3)n[nH]c2=S)cc1
c: Nn1c(SCc2cc([N+](=O)[O-])cc3c2OCOC3)nnc1-c1ccccn1
Answer: a. COc1ccc(Cl)cc1CN1C(=O)NC2(CCCCCC2)C1=O
