B Correct answer
Explanation

During World War II, metals like lead and tin were critical for the war effort, creating severe shortages for civilian goods. This forced manufacturers to switch from metal tubes to plastic for toothpaste packaging, a practice that continued after the war due to cost and convenience. World War I occurred too early for widespread toothpaste tube use, the Civil War predated modern toothpaste packaging entirely, and World War III has not occurred.

AI explanation

During World War II, metals like lead and tin were rationed for military use, so toothpaste manufacturers switched from metal tubes to plastic packaging, a change that stuck permanently afterward. This wartime materials shortage — not World War I or the Civil War — is what forced the packaging switch.
