Step-by-step explanation:
Maria Theresa did not become queen of Austria because her husband died and left the throne to her. The statement is false.
Maria Theresa became queen of Austria through the Pragmatic Sanction, which was a legal document issued by her father, Emperor Charles VI, stating that she would inherit the Habsburg territories. However, her succession was contested by other European powers and led to the War of Austrian Succession.
Despite initial setbacks, Maria Theresa managed to successfully defend her claim and became the ruler of the Habsburg territories, including Austria.
