Which governmental function is primarily concerned with the structure and organization of the House of Representatives?

The correct answer focuses on legislative apportionment, which is the process that determines how many representatives each state receives in the House of Representatives, based on factors such as population. This function is crucial for maintaining an equitable representation in the legislative branch, ensuring that the distribution of representatives reflects the demographics of the states. Apportionment is directly related to the organization and structure of the House, as it influences the number of members and can impact the balance of power among states in the federal government.

The other options, while significant in their own right, do not specifically pertain to the organization of the House of Representatives. For example, judicial review refers to the power of courts to assess the constitutionality of legislative acts and executive actions, while executive orders are directives issued by the President to manage the operations of the federal government. Constitutional amendments relate to the formal changes to the Constitution itself, rather than the internal structure and organization of legislative bodies like the House of Representatives.
