Solution

The correct option is B

rhombus with side 4 cm


In ΔBCD, the points Q and R are the mid-points of the sides BC and CD respectively.
QRDB

and QR=12DB [By mid-point theorem]

Similarly, In ΔBAD, the points S and P are the mid-points of the sides AD and BA respectively.
SPDB

and SP=12DB [By mid-point theorem]

Hence can conclude from above that;

QRPS = 4 cm

Hence, PQRS is a rhombus.
