GENERAL HISTOLOGY

Detailed explanation-1: -Primary oocytes begin the first meiotic division before birth but do not complete prophase 1 and stay dormant until puberty. The cell division is oogonia is arrested at the diplotene stage of prophase I. Thus the correct answer is option B.

Detailed explanation-2: -Oocyte growth occurs concomitantly with follicle growth, but the oocyte remains arrested at prophase I until a preovulatory surge of luteinizing hormone (LH) from the pituitary stimulates meiotic resumption. The prophase I-arrested oocyte acquires the ability to resume meiosis as it approaches its full size.

Detailed explanation-3: -The primary oocyte remains in a resting state, nestled in a tiny, immature follicle until puberty.

Detailed explanation-4: -The primary oocytes (2n) in female ovaries begin their meiosis in the fetal stage but become arrested in prophase I of meiosis I.

Detailed explanation-5: -The primordial ovum enclosed within the primary follicle begins meiosis, but the process is paused at prophase 1 of the first meiotic division by secretions of the granulosa cells that freeze the ovum in this state.
