Task: Answer the MCQ question.
Query: Which compound exhibits a -1.882\% 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: O=C1C=C(c2cccc(O)c2)CCC1
b: O=C(Nc1ccc(-c2ccccc2)cc1)c1ccccc1
c: CCC(C)N=CC1=C(O)C(C(=O)OC)C(C)(C)CC1=O
Answer: c. CCC(C)N=CC1=C(O)C(C(=O)OC)C(C)(C)CC1=O
