Correct Answer Logic:

Least Count ($LC$) of a screw gauge is given by: $LC = \frac{\text{Pitch}}{\text{Number of divisions (N)}}$.

Given $LC = 5 \ \mu\text{m} = 5 \times 10^{-6} \text{ m}$ and Pitch $= 1 \text{ mm} = 10^{-3} \text{ m}$.

$N = \frac{10^{-3}}{5 \times 10^{-6}} = \frac{1000}{5} = 200$.
