The correct answer is (a).
The winners of the 2019 Green Nobel Prize are:
- The Intergovernmental Panel on Climate Change (IPCC) and former US Vice President Al Gore.
The IPCC is an intergovernmental body for the assessment of climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide the world with a clear scientific view on the current state of knowledge about climate change and its potential environmental and socio-economic impacts.
Al Gore is an American politician, businessman, and environmentalist who served as the 45th vice president of the United States from 1993 to 2001 under President Bill Clinton. He is also the founder and chairman of the Alliance for Climate Protection, a non-profit organization that works to raise awareness about climate change and promote solutions.
The IPCC and Al Gore were awarded the 2019 Green Nobel Prize for their “efforts to build and disseminate greater knowledge about climate change and to lay the foundations for the measures that are needed to counteract it.”

(c) Five is incorrect because there are only two winners of the 2019 Green Nobel Prize.
(d) Six is incorrect because there are only two winners of the 2019 Green Nobel Prize.
