Final answer:
Ole Miss did not field in 1944 and 1945 due to World War II, which caused a shortage of players as many were involved in military service, impacting many American college football teams.
Step-by-step explanation:
Ole Miss did not field in 1944 and 1945 because of World War II. During World War II, many American college football teams were unable to play or had significantly reduced teams due to the vast number of men, including athletes, who were drafted or volunteered for military service. The impact of the war on Americans' daily lives was substantial, with changes that included unionized workers agreeing to keep production going by not striking, and overall prosperity not increasing due to inflation, wage controls, and a lack of bargaining power for workers. Hence, the correct answer to the question is B) World War II.
