20 divisions on the vernier scale = 16 divisions of main scale
∴ 1 division on the vernier scale
= 16/20 divisions of main scale 
We know that least count = 1MSD – 1VSD
= 1 mm – 0.8 mm = 0.2 mm
= 1 mm – 0.8 mm = 0.2 mm

Explanation:
Least count refers to the smallest measurement that can be accurately read using a measuring instrument. In the case of a Vernier caliper, it is the smallest measurement that can be read between two scale markings.
The formula to calculate the least count of a Vernier caliper is given by:
Least Count = (Value of one main scale division) / (Total number of divisions on the Vernier scale)
In this case, the value of one main scale division is 1 mm. The Vernier scale has 20 equal divisions which match with 16 main scale divisions.
Calculating the least count:
Least Count = (1 mm) / (20 divisions) = 0.05 mm
Therefore, the least count of the given Vernier caliper is 0.05 mm.
Reasoning:
The Vernier scale is designed to provide a finer measurement than the main scale by using a sliding scale with slightly different divisions. When the Vernier scale is aligned with the main scale, the divisions on the Vernier scale indicate the measurement between two main scale divisions.
In this case, the Vernier scale has 20 divisions which match with 16 main scale divisions. This means that each division on the Vernier scale is slightly smaller than each division on the main scale. By using the Vernier scale, we can measure more precisely than what is possible with just the main scale.
The least count is determined by the smallest measurement that can be accurately read on the Vernier scale. In this case, as calculated earlier, the least count is 0.05 mm, which means that we can accurately measure to the nearest 0.05 mm using this Vernier caliper.
Therefore, the correct answer is option D) 0.2 mm.
