Explanation:

• QUAD - The Quadrilateral Security Dialogue (QSD, also known as the Quad) is a strategic dialogue between the United States, Japan, Australia and India that is maintained by talks between member countries.
• The Quad countries — India, the U.S., Australia and Japan — will conduct the next edition of the high-voltage Malabar naval exercise from August 26 to 29 off the coast of Guam in the face of China’s growing military muscle-flexing in the Indo-Pacific.
• The Malabar exercise started in 1992 as a bilateral drill between the Indian Navy and the U.S. Navy in the Indian Ocean.
  Japan became a permanent member of the exercise in 2015. This annual exercise was conducted off the coast of Guam in 2018 and off the coast of Japan in 2019.
  "Last year, the exercise was hosted in two phases in the Bay of Bengal and the Arabian Sea."
