  1. A
    (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
  2. B
    (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
  3. C

  4. D
    (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)

Solution & Step-by-step Explanation

During Prophase I of Meiosis I:Zygotene: Pairing of homologous chromosomes (Synapsis) occurs.Pachytene: Crossing over occurs between non-sister chromatids.Diplotene: Dissolution of synaptonemal complex; X-shaped structures called Chiasmata become visible.Diakinesis: Terminalization of chiasmata occurs.
