Correct answer: C. 2015
Explanation: The direct answer is C: the Sustainable Development Goals, or SDGs, were adopted in 2015. They are 17 global goals dealing with poverty, hunger, health, education, equality, climate, peace and other needs. Countries agreed to pursue them through the 2030 Agenda, so the target year is 2030, not the adoption year. Option A, 1945, is associated with the founding of the UN, not the SDGs. Option B, 1948, is associated with the Universal Declaration of Human Rights. Option C is correct because the 2030 Agenda and its 17 SDGs were adopted in 2015. Option D, 2000, is associated mainly with the earlier Millennium Development Goals, not the SDGs. Memory cue: SDGs = 2015 for 2030.
