Explanation

The correct match is nominal with marital status, ordinal with movie ratings, interval with latitude degrees, and ratio with distance.

Marital status is nominal, an unordered set of categories.

Movie ratings are ordinal, ranked but without equal intervals.

Latitude in degrees is interval, with equal units but an arbitrary zero.

Distance is a ratio variable with equal units and a true zero.

Only ratio scales permit meaningful statements about multiples or ratios.
