Step 1: The task.
This is a matching question about basic cell biology. We pair each item in the first list with the right item in the second list.
Step 2: First match.
Item I matches C, the cytoplasm, the jelly like material inside the cell where many reactions happen. So I-C.
Step 3: Second match.
Item II matches D, Virchow, the scientist who said new cells come from existing cells. So II-D.
Step 4: Third match.
Item III matches B, the mesosome, an infolding of the membrane in bacteria. So III-B.
Step 5: Fourth match.
Item IV matches A, passive transport, movement of substances without using energy. So IV-A.
Step 6: Conclusion.
Combining all matches gives I-C, II-D, III-B, IV-A. Therefore the correct answer is "I-C, II-D, III-B, IV-A". \[ \\boxed{\\text{I-C, II-D, III-B, IV-A}} \]
