Answer: (B)

a-3, b-5, c-1, d-2

• The occurrence of extrafloral nectaries in Passifloraceae species is very common, and their presence, as well as their shape, has been widely used as a diagnostic characteristic for species or species groups within the genus Passiflora.
• Meristematic cells are tightly packed, and during differentiation to parenchyma, schizogenous spaces develop. Examples of this schizogenous cavities or ducts are resin ducts of Pinus.
• The laticiferous duct is a cavity into which latex is secreted. It is found in a considerable number of angiosperm families. Example - Achras.
• Characteristic hydathodes occur especially at the leaf margins of Garden Nasturtium (Tropaeolum majus).
  

So, the correct answer is 'a-3, b-5, c-1, d-2.'
