to limit the power of the legislative branch
to replace the power of the legislative branch

to remove the power of the legislative branch

Explanation:

The president's veto power is a check - and - balance mechanism. Congress (legislative branch) proposes laws. The president (executive branch) can veto a bill. This is not about replacing, strengthening, or removing the legislative branch's power. It is about limiting it (as the executive branch checks the legislative branch's power to pass laws).

Answer:

to limit the power of the legislative branch
