Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.687\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCOC(=O)c1ccc(NS(=O)(=O)c2cc(-c3nnnn3C(C)C)ccc2OC)cc1
[b] CCCc1n[nH]c(=S)n1Cc1ccco1
[c] O=C(O)CC1(CC(=O)Nc2ccc3ccccc3n2)CCCCC1
Answer: a. CCOC(=O)c1ccc(NS(=O)(=O)c2cc(-c3nnnn3C(C)C)ccc2OC)cc1
