Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.376\% 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] C=CCn1c(C)cc(C(=O)COC(=O)c2cncc(Br)c2)c1C
[b] CCOC(=O)C1CCN(c2cc3c(cc2NC(=O)c2ccccc2OCC)n(C)c(=O)n3C)CC1
[c] CCOc1ccc(NC(=O)COc2ccc3c(c2)OCO3)cc1
Answer: a. C=CCn1c(C)cc(C(=O)COC(=O)c2cncc(Br)c2)c1C
