(D) The condition for the $n^{th}$ bright fringe in a Young's double-slit experiment is given by $y = n \frac{\lambda D}{d}$.Since the position $y$ is the same for both cases, we have $n_{1} \lambda_{1} = n_{2} \lambda_{2}$.Given: $n_{1} = 3$, $\lambda_{1} = 700 \, nm$, and $n_{2} = 5$.Substituting the values: $3 \times 700 = 5 \times \lambda_{2}$.$\lambda_{2} = \frac{3 \times 700}{5} = 3 \times 140 = 420 \, nm$.
