2. it cannot measure anything which is of lesser length
3. it can measure anything which is of lesser length
4. all of these

Q. Least count of vernier calliper is :

1. 
   
   Maximum measurement on main scale / Total number of divisions on scale
2. Minimum measurement on main scale / Total number of divisions on vernier scale
