Answer:
The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".
Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.
They show alternation of generation in which sporophyte is the dominant stage.
The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.
The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.
The gametes fertilize to produce a diploid zygote.
The zygote divides mitotically and matures into the diploid sporophyte.

You could extrapolate from this article that if you eliminated mutations in mitochondria, you could eliminate disease.
Answer: Option C
<u>Explanation:</u>
Mitochondria are found all over our body except in red blood cells. This mitochondria aids in the process of ATP synthesis. Sometimes mutation occurs in the mitochondrial DNA which causes disease in the mitochondria and hence is the root cause of various diseases.
In most cells the mutated mitochondria are removed by the mitophagy which is a natural phenomenon found in all the cells. The mtDNA mutations caused are actually inherited from the mother. Now scientists have developed ways to eliminate the mutated mitochondria from the mother either before or after fertilization. Hence by altering the mutated mitochondria we can eliminate various diseases.
