Show answer and explanation

Correct answer: 0.0 to 0.0

Explanation

Both diodes point from the source's common terminal toward the upper and lower output nodes. On the relevant charging half-cycle, each identical capacitor is charged to the same voltage relative to the source's other terminal.

The upper and lower output nodes therefore attain equal potentials. Their difference across R is zero. This is not the opposite-diode orientation of a voltage doubler. Thus **$V_O=0$ V**.
