The verified answer to “Important Battles question: The Battle of Porto Novo (1781) during the Second Anglo-Mysore War saw British victory under which general?” is Sir Eyre Coote, option B. The source-backed, question-specific record explains: The Battle of Porto Novo (July 1 1781) was fought during the Second Anglo-Mysore War between British forces under Sir Eyre Coote and Hyder Ali's forces. The British won this important battle after their defeats in 1780. 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 B gives Sir Eyre Coote and satisfies every condition stated in the question. The remaining choices—Arthur Wellesley, Robert Clive and Major Munro—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 Sir Eyre Coote without relying on option position.
