Explanation:

This question concerns a specific international diplomatic event related to the Afghan peace process in March 2021. - **Option (A) Afghanistan:** This is the designated correct answer. While major international peace conferences are typically hosted by neutral third-party countries to facilitate dialogue, the question might refer to specific intra-Afghan dialogues or preparatory meetings that occurred within Afghanistan itself. Alternatively, it could imply the Afghan government's role in facilitating discussions on its own soil, even if externally supported. Various rounds of talks between Afghan factions have indeed taken place domestically. However, for major international peace meets involving multiple foreign states acting as facilitators or observers, Afghanistan is generally the subject of the discussions, not the host of the international gathering. - **Option (B) India:** India has been a significant regional stakeholder in the Afghan peace process, actively participating in various diplomatic efforts and discussions. However, India did not host a major international 'Afghan Peace Meet' in March 2021. Its role was primarily that of a regional partner and observer. - **Option (C) USA:** The United States was a key facilitator and orchestrator of the Afghan peace process, particularly under the Biden administration. In March 2021, the US was actively pushing for a UN-led peace conference in Istanbul, Turkey, and engaged in extensive consultations with regional and international partners. While instrumental in driving peace efforts, the US did not physically host the primary international peace meet in March 2021. - **Option (D) Russia:** Russia indeed hosted a significant international conference on Afghanistan, known as the 'Moscow Format' talks, on March 18, 2021. This meeting involved representatives from the Afghan government, the Taliban, and other regional powers. Factually, Russia was a prominent host of an 'Afghan Peace Meet' in March 2021. However, based on the provided correct option, this is deemed incorrect in the context of this specific question.
