This is a subjective question, hence you have to white your answer in the lext-field giver belduw.
a. Temperature is to be measured in the range of 200∘C to 400 ∘C with an accuracy of ±2 ∘C, the sensor is a resistance that varies linearly from 250Ω to 1000Ω for this temperature-range.
b. Power dissipated in the sensor must be kept below 5 mW.
c. Develop analog signal conditioning that provides a voltage varying linearly from - 5 to 5∨ for this temperature range.
