ANS:B - voltage sensitive deflected

For dynamic strain measurement, the Wheatstone bridge used is of voltage sensitive deflected type. In dynamic strain measurement applications, the Wheatstone bridge is commonly used to convert mechanical strain into an electrical signal that can be measured. In a voltage-sensitive deflected Wheatstone bridge configuration, changes in resistance due to strain cause an imbalance in the bridge circuit, resulting in a voltage output that is proportional to the strain applied to the measured object. This voltage signal can then be amplified and processed to obtain dynamic strain measurements. Therefore, the correct option is: voltage sensitive deflected
