Problem statement: Answer the multiple-choice question.
Query: Which compound has a 9.666\% 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, or c without using any other words.
Options:
a O=c1[nH]cc(F)c(=O)[nH]1
b COc1ccc(-n2c(O)c(/C=C/C=Nc3ccccc3)c(=O)[nH]c2=O)cc1
c Cn1nc(C(=O)Nc2nc(-c3ccc(F)cc3)cs2)ccc1=O
Answer: a. O=c1[nH]cc(F)c(=O)[nH]1
