Hint: Liverworts belong to the Marchantiophyta and mosses belong to the Bryophyta. Mosses have tiny and leafy arrangements having radial or spiral symmetry. They are simple in their structure. Liverworts have foliose and thallus. These are green-leaf-like arrangements attached to the stem.
Complete answer:
The sporophyte is less developed in liverwort rather than mosses. The simplest sporophyte is found in Riccia, a liverwort, where it is represented by capsule only. The most complex sporophyte in the moss is found in Funaria. The most advanced sporophyte, due to the presence of intercalary meristem, is found in Anthoceros (a hornwort).
Pinus is a gymnosperm, a monoecious plant (male and female cones are borne on different branches of the same plant).
The plant body of pinus is sporophyte and is differentiated into roots, stem, and leaves. Pinus plant is the sporophyte, heterosporous (producing two types of spores), monoecious.
Homosporous plants- which produce spores of one kind only. The spores of homosporous plants develop into bisexual gametophytes.
In Salvinia, two kinds of spores are produced - micro (small) spores and mega (large) spores. In these plants, the microspores and megaspores germinate and give rise to the male and female gametophyte. They are retained on the parent sporophytes for variable periods.
In the diplontic life cycle, the dominant free-living phase is diploid. The gametophytic phase is represented by single to few celled haploid gametophytes and the sporophyte is photosynthetic. All seed-bearing plants (gymnosperms and angiosperms) exhibit a diplontic type of life cycle.
Hence, options a and d are not correct.
Note:
The sporophyte is less developed in liverwort rather than mosses. A sporophyte is a multicellular stage which is diploid, a phase in which a plant produces diploid spores. Pinus is a gymnosperm and it is monoecious which means having male and female cones are present in the same plant but on different branches.
