In which years were the Olympic Games cancelled due to World Wars?

The correct choice highlights the Olympic Games that were cancelled specifically due to the impact of World Wars. The Games in 1916 were cancelled because of World War I, which created considerable disruption and safety concerns for international gatherings. Furthermore, the 1940 and 1944 Olympic Games were also cancelled as a result of World War II, with the 1940 Games originally scheduled to take place in Tokyo being called off, and the 1944 Games, which were meant to occur in London, also being cancelled due to the ongoing conflicts of the war.

The significance of these cancellations reflects the profound influence that global conflicts can have on international sporting events, as nations prioritize their efforts towards war rather than athletics. The selections that do not include these years miss the historical timeline of cancellations directly tied to both World Wars.
