Quantities: p. Torque; q. Pressure; r. Linear position; s. Temperature.

  1. (i) - (r), (ii) - (s), (iii) - (q), (iv) - (p)
  2. (i) - (p), (ii) - (s), (iii) - (r), (iv) - (q)
  3. (i) - (r), (ii) - (s), (iii) - (p), (iv) - (q)

Show answer and explanation

Correct answer: (C) (i) - (r), (ii) - (s), (iii) - (p), (iv) - (q)

Explanation

An LVDT measures linear position, a thermistor measures temperature, strain gauges on a shaft measure torque, and a diaphragm senses pressure. The correspondence is i-r, ii-s, iii-p, iv-q, giving **C**.
