Answer:

A. It helped him determine his ship's latitude.

Step-by-step explanation:

A jacob staff, is a crossbow shaped instrument that hels measure the distance from the horizon to a certain celestial body, like the stars, the sun, or the moon, by knowing this angle a navigator could then figure out his latitude and direction. It gets his name from the bible, where Jacob crosses the Jordan river using a staff.
