Answer:
A. They could roll over barbed wire in no-man's land, allowing infantries better avenues to assault the other side.
Explanation:
However, it is worth noting that tanks, while they helped break the static warfare nature of World War I, they were not as effective in practice, but rather as a shock factor.
Early tanks had very thin armor, which allowed for even small arm fire to penetrate it at times, ranging from a thickness of 6 - 10mm thick. The amount of protection was close to none, and at times the armor itself created more damage, as penetrating shells would shatter and the armor itself would spall, creating a almost fragment like bomb that peppered the insides of the crew. Enclosed inside a metal casing, the shrapnel would bounce until they lost their inertia. Given that there crews wore little to no protection during that time, it was easy for troops to be damaged by such fragmentation.
Simply put, World War I tanks did not play much more of a role than a shock factor, as their technologies were not advanced enough to to do much else.
