The main scale of a vernier calliper reads $10 \mathrm{mm}$ in $10$ divisions. $10$ divisions of vernier scale coincide with $9$ divisions of the main scale. When the two jaws of the callipers touch each other, the fifth division of the vernier coincides with a main scale division and the zero of the vernier is to the right of zero of the main scale. When a cylinder is tightly placed between the two jaws, the zero of vernier scale lies slightly to the left of $\text{3.2} \mathrm{cm}$ and the fourth vernier division coincides with a main scale division. The diameter of the cylinder is

• Correct answer
  A

  $\text{3.19} \mathrm{cm}$
• B

  $\text{3.14} \mathrm{cm}$
• C

  $\text{3.04} \mathrm{cm}$
• D

  none of these

Hence, the correct answer is option: 'A'.
