Which diagram has all the correct lines of reflectional symmetry for the rectangle?

A
Image with description Rectangle with two dashed diagonal lines connecting opposite corners and intersecting at the center. A dashed vertical line and a dashed horizontal line also pass through the center of the rectangle.
B
Image with description Rectangle with four dashed diagonal lines. The dashed lines connect the midpoint of each side to the midpoint of the opposite adjacent side, forming a diamond shape inside the rectangle.
C
Image with description Rectangle with a dashed vertical line and a dashed horizontal line passing through the center of the rectangle.
D
Image with description Rectangle with two dashed diagonal lines connecting opposite corners and intersecting at the center of the rectangle.
