Answer:
(c) The central bright fringe becomes wider, because the angle that locates the first dark fringe on either side of the central bright fringe becomes larger.
Explanation:
The formula that gives the angle of the first minimum of the diffraction pattern from a single-slit is
where
is the wavelength of the light
w is the width of the slit
We see that the angle is inversely proportional to the width of the slit: therefore, if the width of the slit is reduced (so, w is decreased), the angle that locates the first minimum increases, and so the central bright fringe becomes wider.
