To an observer on a ship at sea at which latitude does the north star appear closest to the horizonn

0 ° latitude,  at the equator

Explanation:

Given the Earth's spherical shape, the North Star, Polaris can be observed relative to the horizon. Its position is dependent on the observer's location;  so, the angle between Polaris and the northern horizon corresponds with latitude.

Latitude is a point's coordinate relative to its location in a north-south position. As an observer on a ship, the North Star, would appear closest to the horizon when viewed at the equator, thus, since the angle between the northern horizon and Polaris is approximately zero, the coordinate is 0° latitude.
