The competition coefficient of species A on species B is 0.25 and the competition coefficient of species B on species A is 2.5. Species C and species D have carrying capacities of 8,000 and 14,000, respectively. The competition coefficient of species C on species D is 0.1 and the competition coefficient of species D on species C is 0.2. Based on the Lotka‒Volterra equation, which of these pairs of species can coexist?

• A) Only species A and species B
• B) Only species C and species D
