Final answer:
Australia has won the ICC Cricket World Cup five times, the most by any country. South Asian countries have collectively won the tournament three times.
Step-by-step explanation:
The country that has won the ICC Cricket World Cup the maximum number of times is Australia. Australia has won the tournament five times: in 1987, 1999, 2003, 2007, and 2015. While the British game of cricket is indeed an important cultural and national sport in South Asia, and intense rivalry exists especially between India and Pakistan, Australia leads the tally in terms of World Cup victories. South Asian countries have won the tournament three times: India lifted the trophy in 1983 and 2011, Pakistan emerged victorious in 1992, and Sri Lanka won in 1996.
