b. tanks

c. submarines

d. telephone

Answer: b. tanks

The inventive innovation that contributed most to getting the social array of the western front mentioned in World War I was the launch of the tank. The first significant use of tanks in war happened during the Battle of Cambrai in 1917; British soldiers employed Mark IV tanks in breaking through the fortified German defenses which had withstood previous attacks of infantry and artillery for long. Mobility of tanks was enabled through their armored platform, where they could overcome trenches and barbed wires, granting protection to infantry while delivering devastating fire to suppress the enemy position . This was one of the technologies that largely contributed in cracking the western front logjams to enable the Allies to recover their conquests and movement.
