III. Organ IV. System
Codes :
Answer: B
In descending order the body parts are system, organ, tissue and cell, which is IV, III, II, I, option B. Cells form tissues, tissues form organs, and organs working together form a system.
Options A and D are ascending or mixed orders, and option C starts with the organ, ahead of the system, and then goes to the cell before the tissue.
A familiar example runs from a muscle cell to muscle tissue, to the biceps as an organ, to the muscular system, and the question asks for that sequence taken from the largest unit down to the smallest.
