[@weakest_aspirant_lost_father]

Pranaam
Good evening respected sir 🙏
For your provided homework👇
Magnesium strips are cleaned before burning, to remove:
A > ম্যাগনেসিয়াম রঙ বা বর্ণ / Magnesium color or color
B > ম্যাগনেসিয়াম অক্সাইড / Magnesium oxide
C > জল / the water
D > ধুলো / the dust
The answer is B > ম্যাগনেসিয়াম অক্সাইড / Magnesium oxide
Reason 👇
A layer of magnesium oxide over the magnesium prevents the interaction of Magnesium with air and will prevent its combustion because combustion requires the interaction of the substance with the air.
