Knight is not an example of an Anglicized word, so b. False.
Knight is of West Germanic origin and evolved from an old english word cniht, which meant 'boy' or 'servant'. It a cognate, so a word of a similar etymological origin, of the German Knecht, Swedish and Norwegian knekt, Dutch knecht and Danish knægt. It has not been adopted to English from any other language - though they are similar, they developed in respective countries simultaneously and independently.
