A monochromatic light passes through a narrow slit and forms a diffraction pattern on a screen behind the slit. As the slit width increases, the diffraction pattern:

O becomes dimmer.

O shrinks with all the fringes getting narrower.

O spreads out with all the fringes getting alternately wider and then narrower.

O remains unchanged.

O spreads out with all the fringes getting wider.

shrinks with all the fringes getting narrower

Explanation:

As the light passes through the slit, the diffraction pattern shrinks, as the waves have more opening to penetrate, and the fringes becomes more narrow as a result of that, The opposite happens as the conditions are reversed.
