B
Let us analyze them:
- Squares have all angles =90∘, which is not true for rhombuses.
- Rectangles have opposite sides equal and all angles =90∘, true for squares.
- Rectangles have opposite sides equal and parallel, true for parallelograms.
- Parallelograms have 4 sides, true for quadrilaterals.
- Parallelograms may have unequal sides, not true for rhombuses.
So, only 2, 3 and 4 are true.
