(B) In meiosis-$I$,the prophase-$I$ is divided into five sub-stages: Leptotene,Zygotene,Pachytene,Diplotene,and Diakinesis.During the Leptotene stage,the chromatin fibres begin to condense and coil to form compact chromosomes.Therefore,the condensation and coiling of chromatin fibres start during the Leptotene stage.
