Which statement best explains why the constitution limits power of the executive branch

I believe the answer is: The Constitution limits the executive branch to keep the president from becoming too powerful.

The laws or regulations that proposed by the president as the head of executive branch cannot violate the constitution in any way. Under such situation, both the legislative and judiciary branch had the basis to overturn the president's proposed law.
