answer:

the right choice is:

c. russian troops were poorly equipped and suffered more

casualties than any other country.

explanation:

the russian army suffered several important defeats, having millions of casualties - dead, wounded, prisoners -and had to retreat before the advance of better german units. supplies were also a major problem. at some moment, russian soldiers refused to fight on and disobeyed officers. that state of chaos and confusion in the front contributed to the fall of the tsar and to the bolshevik revolution of 1917.
