Malaria
Correct Option:
A
Explanation
Cancer is a non-infectious disease because it is caused by uncontrolled growth and division of abnormal cells rather than by transmission of a pathogen from one person to another. AIDS is caused by HIV, tuberculosis by Mycobacterium tuberculosis, and malaria by Plasmodium parasites transmitted through infected female Anopheles mosquitoes.
