Its b. . . . . . . . . . . . . . . . . . . . . . . . . . . 

Your answer is B All squares are rhombuses because with a square if you turn it a certain direction it will make a rhombus also its not A because a rhombus is a different shape then a square its not C because rectangles are bigger than squares therefore rectangles are not squares so that takes out C when it came down to rather B, or D I choose B because parallelograms have sets of parallel lines like a triangle it has one set of parallel lines even though a rectangle has two sets it doesn't make it a parallelogram it makes it a quarduraltou.                                                                                                                                                     Your answer is B.
