Answer:
The correct answer is E. The organelle that is found in both plants and animals is the Mitochondria.
Explanation:
Mitochondria are cellular organelles responsible for supplying most of the energy necessary for cellular activity (cellular respiration). They act as energy plants of the cell and synthesize ATP at the expense of metabolic fuels (glucose, fatty acids and amino acids). The mitochondria has an outer membrane permeable to ions, metabolites and many polypeptides. This is because it contains proteins that form pores called porins or VDAC (voltage-dependent anionic channel), which allow the passage of molecules up to 10 kDa of mass and an approximate diameter of 2 nm.

1. P (because the tick is benefited but the dog isn't.)
2. M (because both organisms are benefited.)
3. P (the tapeworm is benefited but the student isn't.)
4. C (because the bird's nest is benefited and the tree is not harmed)
5. C (the hermit crab needs the sea anemones and the sea anemones is not harmed)
But yeah I gave you a few examples of (P, M, and C), so you should figure it out now.
6. C
7. P
8. M
