The correct statement is: English today is very different from Anglo-Saxon.
To clarify the other statements:
- The Celts did not introduce Anglo-Saxon to English; rather, Anglo-Saxon is a Germanic language that was brought to England by Anglo-Saxon settlers.
- The French did not introduce Anglo-Saxon to English; instead, the Norman Conquest brought a significant amount of French vocabulary into the English language, but Anglo-Saxon (Old English) predates this influence.
- English today is not very similar to Anglo-Saxon; while some words may have their origins in Anglo-Saxon, the language has evolved significantly over the centuries.
