Two suits of battle armor worn by King Hen

问题：

Two suits of battle armor worn by King Henry VIII were discovered, one from the beginning of his reign in 1510 and the other from 1540. Although both suits of armor were made for Henry VIII, the 1540 suit of armor was 40 pounds heavier than the 1510 suit of armor.
Which of the following, if true, contributes LEAST to an explanation of the discrepancy described above ？（）

A．Henry, although slim at the beginning of his reign, developed a bulky figure because of massive weight gain.

B．During his reign Henry increased his arsenal of weapons because, despite his popularity in 1510, by 1540 the English populace was becoming disenchanted with his rule.

C．Although the style of armor was plain and severe in the beginning of Henry’s reign, he started the fashion of decorating armor with heavy and elaborate metal pieces because of his love for ornamentation.

D．Henry ascended the throne while still an adolescent and grew three inches during his first five years as king.

E．Because of the improved design of battle weaponry during the 1530’s, armor was given a multilayered design so that the sharper and per weapons could not pierce it.
