Which term is used to describe the longitudinal axis of a bridge?

Explanation:
The main idea is axis orientation in structural analysis. The longitudinal axis is the line that runs along the length of the bridge, from one end to the other, and is used to describe directions, bending along the span, and related effects. In bridge design we talk about longitudinal bending and forces aligned with that length, which is why the term used for this axis is longitudinal. The other options don’t describe an axis: maintenance refers to keeping the structure in service, luminaire is a lighting fixture, and local buckling is a failure mode of a compressed member, not a directional axis.
