Based on the way living things are organized, what level combines to form tissues?

I was trying to help answer this question to the best of my ability and I did some research and found a website with the link that might be helpful... I had originally posted the information that I thought might be relevant however, It was flagged for plagiarism which was not my intention at all!! I gathered some more information and re-wrote it. I'm not sure I explain quite as well as the original source. "8 Levels of Organization" By: Amanda Soderlind but I gave it my best try!

8levels of living things largest to smallest

1.Organism- Is a singular living article that shows properties of life

2. Organ system- is a group of multiple organs that work together

3. Organ- a part of an organism that is typically self-contained and has a specific vital function. It is made of two or more tissues that work together for a common function

4. Tissue- All living things are made up of cells. Cells are the smallest unit of living things.

• Tissue is a cellular departmental level between cells and complete organs. A tissue is a group of similar cells and their extracellular matrix from the same origin that together carry out a specific function. (Organs then form by the functional grouping together of numerous tissues)

5. Cells- Cells are the basic structures of all living organisms.

6. Organelle- is a very small cellular structure that performs specific functions within a cell

7. Molecule- is a particle made up of two or more atoms that are chemically bonded together

8. Atom: Are the basic units of matter for example- The element of helium

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

i think the answer is b.
