The correct answer is (a) Ebola Fighters.
The Ebola virus disease (EVD) outbreak in West Africa was the largest and most complex Ebola outbreak in history, with more than 28,000 people infected and over 11,000 deaths. The outbreak began in Guinea in December 2013 and spread to Liberia and Sierra Leone.
The Ebola Fighters were the doctors, nurses, and other healthcare workers who risked their lives to treat patients with Ebola. They worked in dangerous conditions, often without adequate protective gear, and many of them became infected with the virus themselves.
The Ebola Fighters were a group of ordinary people who did extraordinary things. They showed courage, compassion, and dedication in the face of a deadly disease. They are an inspiration to us all.
