Explanation:

Suspension bridges use cables to support the deck and carry the load. I - beams (A) are structural elements used in various structures, not a defining feature of suspension bridges. Short spans (B) are not characteristic as suspension bridges can have long spans. Continuous trusses (C) are more associated with truss - type bridges. Cables are the key distinguishing feature for suspension bridges.
