The maximum number of possible interference maxima when slit separation is equal to 4 times the wavelength of light used in a double slit experiment is

In a Young's double slit experiment if the slit separation is twice the wavelength of light used then the maximum number of interference maxima is

In Young's double slit interference experiment, the slit separation is made 3 fold. The fringe width becomes

In Young'double-slit interference experiment, if the slit separation is made threefold, the fringe width becomes

In Young'double-slit interference experiment, if the slit separation is made threefold, the fringe width becomes

The ratio of the intensities at minima to maxima in the interference pattern is 9 : 25. What will be the ratio of the widths of the two slits in the young's double slit experiment ?
