The correct answer is A) Because the Venetians controlled the Mediterranean and Middle-eastern traders controlled the land route to Asia.
A reason why the Portuguese traders and sailors attempted to find an all-water route to Asia was because the Venetians controlled the Mediterranean and Middle-eastern traders controlled the land route to Asia.
Portugal sent out explorers to find an Ocean route to Asia. Portuguese were the first ones to establish a sea trade with Asia, Many merchants exported and imported products. The son of the King of Portugal, Prince Henry, really supported exploration, that is why it was a priority for Portugal. He was known as Henry, the Navigator, for the dedication and support of exploration.
