The United Nations declared 4th week of September as the

Breast Cancer Awareness Month
Week of Solidarity with the Peoples Struggling against Racism and Racial Discrimination
Week of Solidarity with the Peoples of Non-Selfgoverning Territories
Peace Week

The correct answer is: B. Week of Solidarity with the Peoples Struggling against Racism and Racial Discrimination

The United Nations General Assembly proclaimed the International Decade for People of African Descent (2015-2024) in its resolution 68/237 of 23 December 2013. The Decade aims to promote the full enjoyment of all human rights and fundamental freedoms by people of African descent, and to eliminate all forms of racism, racial discrimination, xenophobia and related intolerance against them.

As part of the Decade, the United Nations has designated the 4th week of September as the Week of Solidarity with the Peoples Struggling against Racism and Racial Discrimination. This week is an opportunity to raise awareness of the challenges faced by people of African descent, and to promote solidarity with them in their struggle for equality and justice.

The other options are incorrect because:

  • Breast Cancer Awareness Month is observed in October.
  • The Week of Solidarity with the Peoples of Non-Selfgoverning Territories is observed in the last week of November.
  • Peace Week is observed in the first week of December.
