Answer:
B) Suspend the constitution and arrest opponents.
Step-by-step explanation:
The burning of the Reichstag in February 1933 was used by Hitler and the Nazi Party to justify suspending civil liberties and passing the Reichstag Fire Decree. This decree abolished a number of constitutional protections and allowed the Nazi's to arrest and imprison political opponents. The fire was blamed on communists and used to consolidate Hitler's power.
