Suppose f(x)=x^2 and g(x)=1/4x^2. Which statement best compares the graph of g(x) with the graph of f(x)?

A. The graph of g(x) is the graph of f(x) vertically stretched by a
factor of 4.

B. The graph of g(x) is the graph of f(x) shifted 1/4 units right.

C. The graph of g(x) is the graph of f(x) horizontally stretched by a factor of 4.

D. The graph of g(x) is the graph of f(x) horizontally compressed by a
factor of 4.
