When hydraulic fluid is released upon depressing the air valve core of the accumulator, it indicates a problem with a ruptured diaphragm or leaking seals. The accumulator is designed to store hydraulic fluid under pressure, and if fluid is escaping when the air valve core is pressed, it suggests that there is a breach in the sealing components or diaphragm inside the accumulator. This can lead to loss of pressure, inefficient system operation, or even a potential hazard during aircraft operation.

The other options can be considered incorrect:

- An overfilled accumulator, although possible, would not result in hydraulic fluid being released by the air valve core.

- A faulty air valve might lead to issues with pressurizing or depressurizing the accumulator but not necessarily cause hydraulic fluid to be released.

- A blocked fluid line would rather restrict the flow of hydraulic fluid, causing a different set of issues in the system compared to a ruptured diaphragm or leaking seals.
