Answer:
The correct answer will be option-C
Explanation:
HIV AIDS has been a serious threat to the human population as it has infected about 75 million people worldwide out of which 32 million people have died of the disease.
According to the reports of the WHO and UNAIDS, about 37.2 million people are living with this deadly disease in 2018.
In the given question, 37.2 million people lie between 33 million to 42 million in 2018, so the most appropriate option will be 33 million as the value has not reached 42 million.
Thus, Option-C is the correct answer.
