Hole conduction in a p-channel depletion type MOSFET is associated with:

For a p-channel depletion type MOSFET, the primary charge carriers are holes (positive charges) flowing through a p-type semiconductor channel. The 'depletion' mode means a conductive channel naturally exists at zero gate voltage, and applying a positive gate bias depletes these holes to turn the device off. The correct answer simply mirrors the device described in the question. Hole conduction in a p-channel depletion MOSFET is associated directly with 'p-channel depletion'. Other answers are wrong because n-channel devices use electron conduction, enhancement devices are normally off, and 'q-channel' is a fabricated term.
