Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.197\% 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) CN1CCN(C(=O)c2cc(-c3ccccc3)on2)CC1
(b) O=C(CCC(=O)N1CCOc2ccccc21)Nc1ccccc1Br
(c) CC1(C)CC(=O)C=C(NCCN2CCNCC2)C1
Answer: c. CC1(C)CC(=O)C=C(NCCN2CCNCC2)C1
