28. Critics charged that President Franklin D. Roosevelt's "Court Packing" plan to increase the number of Supreme Court Justices was clearly in conflict with
a. the Supreme Court's practice of judicial restraint.
b. the constitutional principle of checks and balances.
c. attempts of Congress to limit judicial responsibilities.
d. efforts to restrict the number of terms a president could serve.

B.

Explanation:

The 'Court Packing plan' was a plan proposed by President Franklin D. Roosevelt on February 5, 1937. The plan was proposed to expand the number of justices in the Supreme Court to 15. He considered that expanding the number of justices will make justice system more efficient.

But, for critics, the plan was a 'packing' plan because they thought that Roosevelt was trying to neutralize the court to his New Deal plan.

Therefore, they thought that that 'court packing plan' was in conflict with the constitutional principle of checks and balances. Thus option B is correct.
