Answer:
B
types of cells, which work together cooperatively.
Explanation:
The hierarchy for an organism is (small to large):
organelles < cell < tissue < organ < organ system < organism
A tissue is made of one or more types of cells.
For A, although types of acids are in the tissue, the acids make up the cell so the acids are already included.
For C and D, organs and organ systems are larger than tissues. What something is made of must be smaller than what it is.
