The answer would be A. The sun is behind the moon, which casts its shadow on Earth.
In a solar eclipse, the moon blocks the sun, meaning that the moon would have to be positioned in front of the sun. This would mean that the sun is behind the moon, while the moon's shadow is cast on Earth.
Tuberculosis is a bacterial infection caused by <em>Mycobacterium tuberculosis</em>.
It is spread via air when affected people cough, sneeze, spit or speak.
It mostly affects the lungs, thus, damaging the respiratory system. Affected people have difficulty breathing, produce bloody mucus and have a chronic cough.
Antibiotic treatment is used for treating it but many people have developed resistance to the antibiotic treatment, giving rise to a new condition called Multi Drug Resistant Tuberculosis (MDR-TB).
