The verified answer to “Important Battles question: Ahmad Shah Abdali who won the Third Battle of Panipat (1761) was the founder of which modern country?” is Afghanistan, option C. The source-backed, question-specific record explains: Ahmad Shah Abdali (also known as Ahmad Shah Durrani) founded the Durrani Empire which is the modern state of Afghanistan. He is considered the founder of modern Afghanistan and is regarded as 'Father of the Afghan Nation.' This evidence establishes the historical relationship required in this Important Battles item. A correct solution must preserve the exact battle, date, participants, commander, location, outcome or significance requested by the stem. Similar periods, genres or national traditions do not make two battle facts interchangeable. Option C gives Afghanistan and satisfies every condition stated in the question. The remaining choices—Iran, Pakistan and Tajikistan—do not satisfy the complete requirement. The reliable checking method is to identify the named battle first, recall or verify its verified participant or outcome, and then read qualifiers such as “both works,” “original language,” “first published,” “correctly matched” or “incorrectly matched.” These qualifiers determine what counts as the answer. Replaying that method for this Important Battles question confirms Afghanistan without relying on option position.
