What distinguishes the modern presidency from the institution originally envisioned by the framers of the constitution?

I think these are the choices to your question:

a. The modern presidency has become the central focus of American politics since the 1930s, supplanting Congress as the "first branch" of government.
b. The modern presidency is less involved in the development of foreign policy than the framers intended.
c. Modern presidents exhibit a greater level of deference to Congress in budgetary matters than the framers intended.
d. Modern presidents are much less democratic than the framers intended.

I think the answer is, c. Modern presidents exhibit a greater level of deference to Congress in budgetary matters than the framers intended.
