Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.201\% 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=C1NC(=S)N/C1=C/c1ccc2ccccc2c1
b. O=C(Nc1ccc(F)cc1)c1cccc(N2C(=O)C3C4C=CC(C5CC45)C3C2=O)c1
c. CCC1(CC)C(=O)C=CNC1=O
Answer: a. O=C1NC(=S)N/C1=C/c1ccc2ccccc2c1
