| d. LVDT | iv. Stress |
Codes : a b c d

Answer: B
The correct matching is a-iii, b-iv, c-ii, d-i, which is code (B).
A Bourdon tube measures pressure (iii), a strain gauge measures stress through strain (iv), a thermistor measures temperature (ii) and an LVDT measures displacement, which is distance (i).
Codes (A), (C) and (D) connect at least one transducer with the wrong quantity.
Each of these transducers converts the quantity into an electrical or mechanical signal: the Bourdon tube straightens under pressure, the strain gauge changes its resistance with strain, the thermistor changes resistance with temperature and the LVDT gives a voltage in proportion to the core position.
