To understand why this is the correct matching, we can analyze the significance and historical outcome of each world event listed in List-I:

1. United Nations Conference on the Human Environment (1972) matches with (iii) Environmental Movement:
Also known as the Stockholm Conference, this was the United Nations' first major conference on international environmental issues. Held in June 1972 in Stockholm, Sweden, it marked a crucial turning point in global environmental politics. It laid the foundation for modern environmental governance, led to the creation of the United Nations Environment Programme (UNEP), and greatly catalyzed the global Environmental Movement by bringing environmental concerns to the forefront of international policy.

2. Brundtland Report (1987) matches with (iv) The word ‘Sustainable Development’ was introduced:
Officially titled Our Common Future, this report was published in 1987 by the World Commission on Environment and Development (WCED), chaired by Gro Harlem Brundtland. The report is historically significant because it formally defined and popularized the term Sustainable Development, defining it as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."

3. UN Millennium Summit (2000) matches with (i) Millennium Development Goals (MDG):
In September 2000, leaders from 189 nations gathered at the United Nations headquarters in New York for the Millennium Summit. The summit concluded with the adoption of the United Nations Millennium Declaration, which established eight international development goals, known as the Millennium Development Goals (MDGs), to be achieved by the year 2015.

4. UN Summit (2015) matches with (ii) Adoption of Sustainable Development Goals (SDGs):
The United Nations Sustainable Development Summit was held in September 2015. During this summit, the 193 member states of the UN officially adopted the 2030 Agenda for Sustainable Development, titled "Transforming our world: the 2030 Agenda for Sustainable Development". This agenda established the 17 Sustainable Development Goals (SDGs) as a successor to the MDGs.

Combining these individual analyses, we get the matching: 1 matches with iii, 2 matches with iv, 3 matches with i, and 4 matches with ii.
