Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

In a Young's double-slit experiment, the separation between slits is d and
the screen is a distance R from the slits. R is much greater than d and > is
the wavelength of the light. The number of bright fringes per unit width
on the screen is:
d/RX
R/dλ
Rd/λ
X/Rd
Rλ/d
