Task: Answer the multiple-choice question.
Question: Which compound exhibits a 15.223\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C(Nc1ccccc1)O/N=C/c1ccccc1Cl
(b) CCN(CC)CCCN=Cc1c(O)n(-c2ccc(C)cc2)c(=O)c2ccccc12
(c) O=C(Cn1c(C(=O)NCCCN2CCOCC2)cc2sccc21)c1ccccc1
(d) Cc1nn(CC(=O)N(C)c2c(N)n(Cc3ccccc3)c(=O)[nH]c2=O)c(C)c1[N+](=O)[O-]
(e) CCOc1ccc(N(C)S(=O)(=O)c2cnc[nH]2)cc1
Answer: b. CCN(CC)CCCN=Cc1c(O)n(-c2ccc(C)cc2)c(=O)c2ccccc12
