Step 1 — Check reaction (1): 
- Cu:  (oxidised) and  (reduced)
- Same element simultaneously oxidised and reduced → Disproportionation ✓

Step 2 — Check reaction (2): 
- Mn in : 
- Mn in :  (oxidised)
- Mn in :  (reduced)
- Same element (Mn) simultaneously oxidised and reduced → Disproportionation ✓

Step 3 — Check reaction (3): 
- Mn in : 
- Mn in :  (reduced)
- Mn in :  (reduced)
- O in : ; O in :  (oxidised)
- Different elements change: Mn is only reduced, O is oxidised → NOT disproportionati
