Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.993\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(COc1ccccc1)N1CCNC1=O
b: CC(C)CN1CCNC(=O)C1CC(=O)N1CCN(C2CCCCC2)C(=O)C1
c: CCOc1ccc(N2C(=O)/C(=C/c3ccc(C)o3)C(=O)NC2=S)cc1
Answer: a. O=C(COc1ccccc1)N1CCNC1=O
