Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.162% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCOC(=O)C1=C(COC(=O)COc2ccc(Br)cc2)NC(=O)NC1C
[b] COc1ccc(NC(=O)c2n[nH]c(=O)c3ccccc23)cc1S(=O)(=O)N1CCCCC1
[c] COc1ccccc1C1NC(=O)NC(C)=C1C(C)=O
[d] O=C(NCCCO)C(=O)NCc1ccncc1
Answer: a. CCOC(=O)C1=C(COC(=O)COc2ccc(Br)cc2)NC(=O)NC1C
