(D) $BaSO_4$ (Barium sulfate) contains Barium,which is a heavy element with a high atomic number $(Z = 56)$.Because of its high atomic number and density,it is highly effective at absorbing $X$-rays.When a patient drinks a $BaSO_4$ suspension,it coats the lining of the stomach.Since $BaSO_4$ absorbs $X$-rays more strongly than the surrounding soft tissues,it creates a high-contrast image on the $X$-ray film,allowing doctors to clearly examine the structure of the stomach.

The patient is asked to drink $BaSO_4$ for examining the stomach by $X$-rays because $X$-rays are
