The correct answer is A. It helped explorers travel at sea

Explanation:

The astrolabe is a complex instrument that was first invented in Ancient Civilizations. This instrument was first designed for astronomers but was later used by mariners as it allowed them to travel at sea more precisely. Indeed, the astrolabe was used to calculate the time of the day, and know the latitude of the ship (location from North to South in the globe) by considering the location of stars and the sun. This means, through the astrolabe explorers could better know their location, which was essential to follow a specific route. Thus, this was an important invention in the area of exploration as it helped explorers to better travel at sea.
