Which among the following organisations released the World Population Report, 2021?

1. A

   International Monetary Fund

   The International Monetary Fund publishes World Economic Outlook and fiscal monitors, not the World Population Report, 2021. This option is not the key.

2. B

   United Nations Population Fund

   The United Nations Population Fund released the World Population Report, 2021 (the State of World Population report). UNFPA is the UN body for population and reproductive health, and this annual flagship is its product. That makes (b) the official key.

3. C

   World Health Organisation

   The World Health Organisation issues World Health Statistics and disease reports, not this population flagship. This option is therefore wrong.

4. D

   United Nations Development Programme

   UNDP publishes the Human Development Report, a different flagship. It did not release the World Population Report, 2021. This option is not the key.

Summary. Official key is (b) United Nations Population Fund. The 2021 world population flagship is a UNFPA publication. IMF, WHO and UNDP issue other well-known reports that exams often mix with UNFPA. World Population Prospects from UN DESA is a separate series. Only (b) is correct for this named report.
