Solution

(a) The central fringe will be white.

(b) There will not be a completely dark fringe.

(d) The fringe next to the central will be violet.

 

The superposition of all the colours at the central maxima gives the central band a white colour. As we go from the centre to corner, the fringe colour goes from violet to red. There will not be a completely dark fringe, as complete destructive interference does not take place.
