Answer:
D)Lycophyta
Explanation:
The seedless vascular plants or the pteridophyte forms one phylum of the plant kingdom. The pteridophyte kingdom can be classified into three groups: the Sphenophytes, the pteridophytes and the Lycophytes.
The Lycophyte group contains about 1000 living species as it is the most primitive group of vascular plants.
The species is characterised by the presence of the microphyll like the Selaginella and Lycopodium.
The rhizoids of the gametophyte of these plants form the mycorrhizal association with the fungi.
Thus, Option-D is the correct answer.
