It is a fern and belongs to Phylum Pterophyta
Fern is a plant with fronds that are attached to rhizomes. The frond is the leaf of the fern and the rhizome is the root which grows. They have vascular tissue which means that they use tubular structures to transport nutrients throughout the plant. They reproduce by spores and have neither seeds nor flowers.

<em>G1, S and G2 phases are all cumulatively referred to as interphase involving the growth of a cell and the replication of its DNA. Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents. The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed the G1 checkpoint and has grown enough to contain double the DNA. S phase is halted by a protein called p16 until this happens.</em>

Answer:
This question have two parts.
Question 1. Is a 0.185 M aqueous solution of sodium sulfate, Na2SO4, hypertonic, hypotonic or isotonic to red blood cells?
Answer:
Hypotonic because sodium sulfate is a detergent which can cross the lipid bi-layer.
Question 2. If normal red blood cells were suspended in this Na2SO4 solution, what would be the expected outcome?
Answer:
Hemolysis (Bursting of Red blood cells) will occur due to excessive movement of water inside the cell resulting from sodium sulfate solution.

It's A, because it's always important to drink water. If you think about it, all the other answers seem invalid.
