Answer
Correct option is
C
(i) Nucleoplasm, (ii) Mitochondria, (iii) Chloroplasts, (iv) Ribosomes
The nucleoplasm is a viscous fluid enclosed in a double-walled membrane of the nucleus.
The mitochondrion is a membrane-bound organelle found in most eukaryotic cells. These structures are sometimes described as "the powerhouse of the cell" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.
Chloroplasts are organelles, specialized subunits, in plant and algal cells. Their main role is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, and stores it in the energy storage molecules ATP and NADPH while freeing oxygen from water.
Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains. Ribosomes are special because they are found in both prokaryotes and eukaryotes. Thus, the correct answer is option C.
