She officially became queen in June of 1953.The queen is part of the last generation of Britain's royal family tobe educated at home. The Associated Press reports that she is thefirst British ruler to have sent an email (1976) or use Twitter, thesocial networking service (2014). Royal historian Hugo Vickerssays that during her rule, Queen Elizabeth has remaineddutiful to her country. He adds that she is known as the'most invisible visible public woman in the world.' How old was Queen Elizabeth Ⅱ when she became the official head of state? 新闻中提到，1952年，伊丽莎白二世25岁时开始执掌政权，1953年她正式成为英国女王，很容易推知她正式成为英国君主时是26岁，故选项B正确。选项A是强干扰项，题目问的是伊丽莎白二世正式成为女王时的年龄，而不是她开始执政时的年龄。
