Explanation:

Both statements 1&3 are correct.

• Malaria is a life-threatening mosquito borne blood disease caused by plasmodium parasites. It is predominantly found in the tropical and subtropical areas of Africa, South America as well as Asia. 
• The parasites spread through the bites of infected female Anopheles mosquitoes.
• After entering the human body, parasites initially multiply within the liver cells and then attack the Red Blood Cells (RBCs) resulting in their rupture.
• Africa carries the world’s largest disease burden for Malaria.
• In Africa, 94% of global cases and 96% of global deaths have been recorded. It is alarming that children aged five or younger account for 80% of these deaths. 

Hence option 3rd is correct.
