(N/A) The cell arrested in the diplotene stage is the primary oocyte in female mammals.
In the primary oocyte, meiosis begins during embryonic development but halts at the diplotene stage of prophase-$I$, a state known as the dictyate stage. This arrest is maintained until puberty, when hormonal signals (specifically the $LH$ surge) trigger the resumption of meiosis, allowing the cell to complete meiosis-$I$ and proceed to meiosis-$II$.
