(c)

For a slit of width light of wavelength when light falls on the slit, the diffraction patterns so obtained as The first diffraction minimum occurs at the angles given by From the equation, it is clear that width of the central diffraction maximum is inversely proportional to the width of the slit.  On increasing the width size , the angle at which the intensity first becomes zero decreases, resulting in a narrower central band and if the slit width is made smaller, the angle increases, giving a wider central band.
