Define the left branch of a quadratic function as the portion to the left of its vertex, and similarly, define the right branch. Let f(x)f(x) and g(x)g(x) be two quadratic functions.

Statement PP: If g(x)g(x) is a translation of f(x)f(x), then the left branch of g(x)g(x) and the left branch of f(x)f(x) intersect at one point, and the right branch of g(x)g(x) and the right branch of f(x)f(x) intersect at one point.

Which of the following is correct?

AStatement PP is correct
BThe converse of Statement PP is correct
CThe contrapositive of Statement PP is correct
DNone of them are correct
