(A)What is the shape of the interference fringes on the screen?

certain wavelengths are missing. Match the options of the columns. In young's double experiment two slits are illuminated with seperation between them as b. The screen is at a distance d ( >>b 0 from slits. At a point Pon the screen directly in front of one of the slits
