Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.685\% 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 other words.
Options:
[a] CCOC(=O)C(=NCCCN(C)C)NNc1ccc(Br)cc1
[b] CCCC(=O)c1cc2c(cc1NC(=O)c1cccs1)OCCO2
[c] COC(=O)N/N=C(\C)c1ccc(Br)cc1
[d] O=C(c1ccc(COc2ccccc2Br)o1)N1CCCCCC1
[e] COc1ccc(C(=O)N/C(=C\c2ccc(Cl)cc2)C(=O)NCC2CCCO2)cc1
Answer: a. CCOC(=O)C(=NCCCN(C)C)NNc1ccc(Br)cc1
