Why is a bridge-type sensor commonly used for pressure measurement?

• A. Pressure sensors often use piezoresistive elements in a Wheatstone bridge format to convert pressure-induced resistance changes into a differential voltage.
• B. A single resistor in series with the supply is sufficient.
• C. Bridges are only useful for temperature measurement.
• D. Piezoelectric crystals are always preferred for pressure measurement.
