Answer 1

The correct answer is (d) A square is a particular case of a rectangle only

The best I can explain: Square is a combination of the properties of a rectangle and a rhombus, i.e. with four congruent sides similar to rhombus and with four right angles same as of rectangle. This can be understood from the figure below.
