   sizeof(2.19f) here '2.19f' specifies the float data type. Hence size of float is 4 bytes.
   
   sizeof(2.19) here '2.19' specifies the double data type. Hence size of float is 8 bytes.
   
   sizeof(2.19l) here '2.19l' specifies the long double data type. Hence size of float is 10 bytes.

   Correct Option: B
