Correct answer
C. (b), (a), (c), (e), (d)
Step-by-step solution
The order of events during prophase I of Meiosis-I is as follows: Leptotene Thickening of chromosome Zygotene Synapsis of chromosome Pachytene Crossing over Diplotene Dissolution of synaptonemal complex Diakinesis Terminalisation of chiasmata.
