The nuclear problem seen in the gland is

• A. Nuclear bubbling
• B. Nuclear swelling
• C. Nuclear pyknosis
• D. Nuclear vacuolation

Answer: (A)

Nuclear changes in glandular tissue reflect how the nucleus responds to injury or processing, often presenting as distinct patterns of vacuolization or chromatin changes. The term nuclear bubbling describes bubble-like vacuoles appearing within the nucleus, giving a bubbled appearance. This pattern points to a nuclear-specific alteration seen in glandular sections and is the best match among the options for describing a nuclear problem in glands.

Nuclear swelling is a more general increase in nuclear size, not a bubble pattern. Nuclear pyknosis refers to a condensed, darkened nucleus typical of irreversible injury. Nuclear vacuolation implies vacuoles, but not the same bubble-like nuclear appearance described here.
