Explanation / Answer

Strain gauge pressure transducer basically measures strain in a peizoelectric material and converts it into potential difference that can be used to measure pressure. What's most important here is to note that strain is the most important thing so we need something that creates strain i.e. any form of pressurebe it gauge, vacuum, absolute or differential, if it is large enough to create starin in the peizoelectric crystal, pressure can be measured.

Therefore the correct answer to this question is c.
