Task: Answer the multiple choice question.
Question: Which compound has a 8.403\% 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, or d without using any additional words.
Options:
(a) CCOc1ccc(-n2nc(C(=O)NCCOC)c3ccccc3c2=O)cc1
(b) O=[N+]([O-])c1ccc(C[n+]2cc(-c3ccccc3)n3c2CCCCC3)cc1.[Br-]
(c) O=C(Cc1n[nH]c(=O)c2ccccc12)Nc1cccc(S(=O)(=O)N2CCCC2)c1
(d) O=C(C1CC(=O)N(C2CCCCCCC2)C1)N1CCC2(CC1)OCCO2
Answer: a. CCOc1ccc(-n2nc(C(=O)NCCOC)c3ccccc3c2=O)cc1
