The Roosevelt administration created the Emergency Banking Relief Act in 1933 to address the banking panic and the overall banking crisis.
Knowing this, lets take a look at the options:
to create a national bank that could be relied on by citizens - Nope
to create an influx of capital to failing banks - This seems to be the best option, all of the others
to monitor banks and issue approval to those that were still sound - As long as the bank was running, they where happy.
to regulate the use of bank holidays among the states- Nope, they issues an enormous bank holiday to shut down the banking system.
B seems to be the best option.
I hope this helps! :)
