The correct answer is:
The central fringe will be white.
Young's double slit experiment with white light which consist wavelength from range $4000 Å$ to $7000 Å$
$\because$ At the centre of the screen, the path difference is zero for all wavelengths. The bright fringes of these wavelengths overlap at the centre. Thus, the white fringe at the centre is formed.
