The correct answer is - A) settling competition over colonized territories.

The Treaty of Tordesillas is a treaty that was conducted between the Portuguese and the Spanish, with the Pope in the middle as a mediator. The purpose of the treaty initiated by the Pope, was to prevent a conflict between two Catholic countries, so he marked a line, from which the western parts were free to take over and be controlled by the Spanish, and on the east of it, the Portuguese were free to take over and control.

This pretty much gave these two countries a permission to take over the whole New World, and they tried their best indeed.
