Please refer to Figure $3,$ which shows the pattern of interference fringes for light of wavelength $647$ nm passing through two narrow slits, projected onto a screen a distance of $1\mathrm{.}68$ m away. The distance on the screen between the centers of two adjacent bright fringes is $1\mathrm{.}66$ cm$.$ What is the distance between the two slits?

Question $10$ options:

a: $1\mathrm{.}05$E$-04$ m

b: $7\mathrm{.}86$E$-05$ m

c: $5\mathrm{.}24$E$-05$ m

d: $6\mathrm{.}55$E$-05$ m
