Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.443\% 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, c, d, or e without using any additional words.
Options:
[a] CCc1ccc(NC(=O)N[C@H](C(=O)O)C(C)CC)cc1
[b] CCCCn1nnnc1SCC(=O)c1cc(Cl)ccc1OC
[c] Cc1cc(C(=O)COC(=O)c2ccc(O)cc2)c(C)n1CCc1ccc(F)cc1
[d] Fc1ccc(-n2cc(CNCCc3ccccn3)c(-c3ccccc3Cl)n2)cc1
[e] COc1ccc(C=C(C(C)=O)C(C)=O)cc1OC
Answer: a. CCc1ccc(NC(=O)N[C@H](C(=O)O)C(C)CC)cc1
