Task: Answer the multiple choice question.
Question: Which compound exhibits a -4.880\% 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) O=S(=O)(Nc1cccc(-c2ccc(N3CCOCC3)nn2)c1)c1ccc(Cl)c(Cl)c1
(b) CN(CC(=O)O)S(=O)(=O)c1ccc2[nH]c(=O)c(=O)[nH]c2c1
(c) Cc1c(NC(=O)C(=O)/C=C(\O)c2ccc(Cl)cc2)c(=O)n(-c2ccccc2)n1C
(d) COc1ccccc1CCNC1CCCCCC1
(e) O=C1c2oc3ccccc3c(=O)c2C(c2cccs2)N1CCCN1CCOCC1
Answer: b. CN(CC(=O)O)S(=O)(=O)c1ccc2[nH]c(=O)c(=O)[nH]c2c1
