The primary coil of a linear variable differential transformer (LVDT) is supplied with AC voltage as shown in the figure. The secondary coils are connected in series opposition and the output is measured using a true RMS voltmeter. The displacement

of the core is indicated in mm on a linear scale. At the null position

, the voltmeter reads 0 V. If the voltmeter reads 0.2 V for a displacement of

mm, then for a displacement of

mm, the voltmeter reading, in V, is

In the force transducer shown in Figure (a), four identical strain gauges S1, S2, S3, and S4 are mounted on a cantilever at equal distance from its base. S1 and S2 are mounted on the top surface and S3 and S4 are mounted on the bottom surface, as shown in the Figure (a). These strain gauges are to be connected to form a Wheatstone bridge consisting of four arms A, B, C, and D, as shown in Figure (b). From the following options, the correct order to maximize the measurement sensitivity is
