Friction tends to oppose any relative motion between objects, acting at the surfaces in contact. If there is relative motion, the frictional force is the kinetic force of friction. If there is no relative motion, the frictional force is the static force of friction.

B. Lycophyte sporophyte
Explanation:
Lycophytes belong to the division Lycophyta under Pteridophyta. Lycophytes are group of seedless vascular plants.
The living lycophytes are representatives of a plant group that were dominant during the carboniferous period. The extinct groups of lycophytes were mostly tree like tall and large e.g. <em>Lepidodendron</em>
However, the modern day lycophytes are small and herbaceous. They show alternation of generation with the sporophyte being the dominant phase. The leaves are small and simple with an unbranched midrib,these are called microphylls.
The reproduction in lycophytes takes place through spores which are produced inside a sporangia. Specialized leaf like structures called sporophyll bear the sporangia. These sporophylls may or may not be present at the terminal ends of branches and are arranged into definite strobili.
Keeping all these features in mind and comparing the characters of the plant found by the student, we can conclude that the plant is more likely to be a lycophyte sporophyte.
