Answer: D. Wells wanted to illustrate that England could be caught with its guard down .
Explanation:
"War of the Worlds" was first published in 1897 which was a time when people were not much worried about aliens. They were at the time, more worried about European powers like Germany that were threatening British supremacy.
H. G. Wells chose aliens to attack England instead to show that they could be caught with their guard down on account of being worried about a single enemy when there were other enemies out there to be worried about.
