   A miniaturized research probe enters a photosynthetic plant cell and traverses two boundary membranes, emerging into a fluid-filled internal chamber rich in metabolic enzymes and circular DNA. The vessel then hovers alongside a towering stack of flattened, pigment-bearing membranous discs actively carrying out the primary light reactions. Which pair correctly identifies the internal fluid chamber surrounding these structures and the individual flattened sacs that compose the stacks?

   • A) Stroma and thylakoids
   • B) Matrix and cristae
