B. Image B: rectangle

C. Image C: square

D. Image D: regular pentagon

E. Image E: regular hexagon

plz help me

A figure with a rotation symmetry will look the same, when rotated. The figures with rotation symmetry are:

B: rectangle

C: square  

E: regular hexagon

For a shape to have a rotation symmetry, the following must be true.

Options (a) and (d) do not meet any of the above conditions.

However, the stated conditions are true for options (b), (c) and (e); because they have parallel & equal opposite sides; and they have an even number of sides.

Hence, the rectangle, the square and the regular hexagon have a rotation symmetry

See attachment for an illustration of rotation symmetry.
