Which of the following describes a clinical sign of giant papillary conjunctivitis (GPC)?

Explanation:
Giant papillary conjunctivitis shows large, cobblestone-like papillae on the upper eyelid’s tarsal conjunctiva, and these papillae are typically more than 1 mm in diameter and can involve the entire upper lid surface (across all five zones). This widespread, sizable papillary reaction is the hallmark of GPC and helps distinguish it from milder or different forms of conjunctivitis. In contrast, signs described as papillae limited to the lower lid margin, or papillae that are flat and non-palpable, or papillae smaller than 0.5 mm, do not fit the characteristic presentation of GPC.
