The correct answer is: A. Weimer Constitution of Germany.
The Weimar Constitution was the constitution of the German Weimar Republic from 1919 to 1933. It was the first modern democratic constitution in Germany, and it established a federal republic with a strong president and a weak parliament. The constitution also included a number of fundamental rights, such as freedom of speech, freedom of assembly, and freedom of religion.
The provision of suspension of fundamental rights was borrowed from the Weimar Constitution because the framers of the Indian Constitution wanted to ensure that the government could take emergency measures in times of crisis without having to amend the constitution. The Weimar Constitution had a provision that allowed the government to suspend fundamental rights in times of emergency, and the framers of the Indian Constitution felt that this was a necessary safeguard.
The other options are incorrect because they do not have a provision for the suspension of fundamental rights. The Australian Constitution does not have a bill of rights, and the American Constitution only protects certain fundamental rights, such as freedom of speech and freedom of religion. The Canadian Constitution does have a bill of rights, but it does not allow the government to suspend fundamental rights in times of emergency.
In conclusion, the provision of suspension of fundamental rights is borrowed from the Weimar Constitution of Germany. This provision was included in the Indian Constitution to ensure that the government could take emergency measures in times of crisis without having to amend the constitution.
