Hoover's response to the Great Depression was the Smoot-Hawley tariff which rose tariffs on over 20,000 products. This measure led to retaliation from foreign countries especially from Europe and they rose their own tariffs on their American imports, the American economy was hit back and it explains why Hoover's policy failed.
Hoover was nicknamed "Do nothing" by the Democrats, they blamed him for sticking to Laissez faire economics, but this accusation was wrong as he pushed for more state intervention which eventually failed.
The best answer is:
"C" More troops.
They were better trained, more equipped, and definitely had a much larger quantity.
I hope this helps!
