Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a -0.632\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCOc1cc(/C=C/C(=O)c2ccc(OC)c(CN3CCOCC3)c2)cc(Br)c1O
b O=c1oc(-c2ccccc2)cc(Cl)c1Cl
c CCOC(=O)c1ccc(NC(=O)c2n[nH]c(=O)c3ccccc23)cc1
d O=c1c2c(nc3nc[nH]n13)CCC2
Answer: d. O=c1c2c(nc3nc[nH]n13)CCC2
