The accurate statement among those you've provided is:
"Beisbol is more important than futbol in Cuba, Puerto Rico, and la República Dominicana."
In those countries, baseball (beisbol) has a strong cultural significance and passionate following. While fútbol (soccer) is extremely popular in many Spanish-speaking countries, it is not the predominant sport in Cuba, Puerto Rico, and the Dominican Republic, where baseball holds a more central place in the national sports culture.
The other statements are not accurate; for example, fútbol is generally considered the most popular sport in most Spanish-speaking countries, including Mexico and Argentina.
