The correct answer is C: drafted a new constitution.
The coup d'etat in Brasil in 1964 overthrew the reformist government of President Joao Goulart and established an authoritarian regime controlled by the armed forces that lasted until 1985.
After the change of government, the new regime kept the 1946 constitution but wanted to change it because the measures they took in the country were against it.
<em>A new constitution was written</em> by a team of lawyers supporting the new oppressive system. The main feature of the new constitution of 1967 were: restriction of political rights, restriction of civil rights, removal od all privileges for judges, strengthening the role of the State Military Police, the control of political parties, giving more power to the president.
Amendments to the constitution were drafted in 1969.
