Task: Answer the multiple-choice question.
Question: Which compound exhibits a -5.789\% human ether-à-go-go related gene (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) CN1C(=O)S/C(=C/c2cccnc2)C1=O
(b) CN(CC(=O)NCc1ccccc1)Cc1ccc(Cl)cc1
(c) O=S(=O)(c1cccc(-c2csc(-c3cccnc3)n2)c1)N1CCOCC1
(d) Cc1ccccc1N/C(SCc1cccc(Br)c1)=C(/C#N)C(N)=O
(e) Cn1c(=O)c([N+](=O)[O-])c(NCc2ccccc2Cl)c2ccccc21
Answer: a. CN1C(=O)S/C(=C/c2cccnc2)C1=O
