The phylum of seedless vascular plants has about 1000 known living species, including those in the genera
Lycopodium and Selaginella; the gametophyte of some of these species cannot photosynthesize, and instead uses
mycorrhizae to obtain nutrients

a. Hepatophyta
b. Monilophyta
c. Bryophyta
d. Lycophyta
e. Anthocerophyta

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.

burning of wood and coal

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.
