Answer:(a) Only one
The statement that recently all the countries of the United Nations have adopted the first-ever compact for international migration, the 'Global Compact for Safe, Orderly and Regular Migration (GCM)' is correct. The GCM was adopted in December 2018 by the United Nations General Assembly.
The statement that the objectives and commitments stated in the GCM are binding on the UN member countries is incorrect. The GCM is a non-legally binding agreement, meaning that its provisions are not legally enforceable.
The statement that the GCM addresses internal migration or internally displaced people in its objectives and commitments is incorrect. The GCM specifically focuses on international migration and does not cover internal migration or internally displaced people.
