The correct answer is option B
The Emperor Hadrian ordered his soldiers to construct a massive Roman Wall across Northern Britain (Roman Britain) to separate it from Scotland in A. D 122. He was a ruler that determined to consolidate the Roman Empire’s borders.
The wall was built to keep out the undefeated people of Scotland. It was made from turf which ran from Wallsend in the east to Bowness on the Solway Firth. It was 80 Roman miles (73.5 modern miles or 117 kilometers) long.
The Hardian wall was the northern border of the Roman Empire. It took about 14 years to complete the construction of the wall. It is now an important and an attractive tourist center in North England.
