A. They illustrate how English language has changed over time

Explanation:

Paston letters were letters written by different members of the Paston family, revealing details of the life of the British nobility in the Middle Ages. The cards range from themes such as unrequited love to intrigue and scamming among family members. Because they were written in the Middle Ages, these letters were written in an archaic English, very different from the English we speak today, so these letters are important in illustrating how the English language has changed over time.
