Correct answer: A — Craniopharyngioma

A suprasellar calcified cystic mass with endocrine dysfunction (growth failure, delayed puberty, diabetes insipidus) and bitemporal hemianopia (chiasmal compression) is characteristic of craniopharyngioma. Despite being histologically benign, surgical management is challenging due to proximity to the hypothalamus. Many patients require lifelong hormone replacement.
