The relationship between gravitational and electrical forces in terms of their classification is best identified as action-at-a-distance forces. Both gravitational and electrical forces operate without the necessity for physical contact between the objects involved. This means that they can exert forces over a distance through fields — the gravitational field for gravity and the electric field for electricity.

Gravitational force acts between two masses, and it can influence an object even if it is not in direct contact with the other mass. Similarly, electrical forces act between charged particles, demonstrating a capacity to exert influence over distance without direct touch. This property of acting over a distance is fundamental in understanding how these forces operate in many physical contexts, such as the influence of the Earth's gravity on an object, or the attraction between charged particles in an electrical context.

The choice highlighting the contact forces incorrectly categorizes both types of forces. While there are forces that require contact, such as friction or tension, gravitational and electrical forces do not fall into that category. Therefore, recognizing them as action-at-a-distance forces provides a clearer understanding of their nature and interaction in the physical world.
