Task: Answer the multiple choice question.
Question: Which compound has a 13.085\% human ether-à-go-go related gene (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] COC(=O)[C@H](CC(C)C)NC(=O)N1CCCCC1C
[b] Cc1ccc(Cn2c(C(C)Nc3nc(-c4ccc(F)cc4)cs3)nc3cc(Cl)c(Cl)cc32)cc1
[c] COc1ccc(C2(c3ccc(OC)cc3)NC(=O)N(CC(=O)Nc3ccccc3)C2=O)cc1
Answer: a. COC(=O)[C@H](CC(C)C)NC(=O)N1CCCCC1C
