The answer is "A) tension force".
A suspension bridge is a sort of extension in which the deck (the heap bearing bit) is hung underneath suspension links on vertical suspenders. The primary present day cases of this kind of scaffold were worked in the mid 1800s. Simple suspension bridges, which need vertical suspenders, have a long history in numerous uneven parts of the world.
This kind of bridge has links suspended between towers, in addition to vertical suspender links that convey the heaviness of the deck underneath, whereupon activity crosses. This game plan enables the deck to be level or to circular segment upward for extra freedom.
