Given Data:
- Distance between the coherent sources (d) = 0.90 mm = 0.90 x 10^-3 cm
- Distance between the fringes (Y) = 1 mm = 1 x 10^-3 cm
- Distance to the screen (L) = 1 m

Formula:
The formula to calculate the distance between fringes in a Young's experiment is given by:
Y = λL/d

Calculation:
Substitute the given values into the formula:
1 x 10^-3 = λ x 1 / 0.9 x 10^-3
λ = 0.9 x 10^-3 / 1 x 10^-3
λ = 0.9
Therefore, the wavelength of the monochromatic light used is 0.9 x 10^-4 cm.
The closest option to this value is option 'D' which is 6 x 10^-5 cm.
