In a young's doule slits experiment, a monochromatic source of wavelength `lambda` is used to illuminate the two slits

`S_(1)` and `S_(2)`. The slitss `S_(1)` and `S_(2)` are identical and source S is placed symmetrically as shown. interference pattern is observed on a screen at a distance D from the centre of slit. The distance between the slits is d.
If the source is moved up by a very small distance `y_(0)`, the central maxima will shift

A

Up by `(y_(0)d)/(x_(0))`

B

Down by `(y_(0)d)/(x_(0))`

C
