Ecologist has proposed following explanation to lead biodiversity at tropic.
a) Higher productivity in the tropics allows for more species
b) Environments are more stable and predictable in the tropics, with fairly constant temperatures and rainfall levels year-round
c) Predators and pathogens limit competition in the tropics, which allows more species to coexist
d) High evolutionary speed at tropic than temperate

Two islands, P and Q, are similar in habitat and other features. They are 100 and 200 km2 in size respectively, but have the same number of species. Which of the following statements can independently explain this observation?
(i) P is closer to the mainland than Q
(ii) P is further away from the mainland than Q
(iii) P has higher speciation rates than Q
(iv) P has lower speciation rates than Q
