Two instruments are described: (i) a Vernier callipers with 1 MSD=0.05 cm and 1 VSD=2.45/50 cm; (ii) a screw gauge of pitch 0.5 mm whose circular-scale division corresponds to 0.01 mm. Select the correct statement about their least counts and precision.

Options

• Option A

  Both the instruments have same least count.

• Option B

  Least count of screw gauge is lesser than that of vernier callipers.

• Option C

  Both the instruments have same least count but screw gauge is more precise.

• Option D

  Both the instruments have different least count and screw gauge is more precise.
