Step 1: The task.
We match types of chromosomes to the position of their centromere. The centromere is the pinched point that decides the chromosome shape.
Step 2: First match.
Item I is metacentric, C, where the centromere sits right in the middle, giving a V shape. So I-C.
Step 3: Second match.
Item II is sub-metacentric, B, where the centromere is slightly off the center, giving an L shape. So II-B.
Step 4: Third match.
Item III is acrocentric, D, where the centromere is near one end. So III-D.
Step 5: Fourth match.
Item IV is telocentric, A, where the centromere is right at the tip or terminal end. So IV-A.
Step 6: Conclusion.
Putting it together gives I-C, II-B, III-D, IV-A. Therefore the correct answer is "I-C, II-B, III-D, IV-A". \[ \\boxed{\\text{I-C, II-B, III-D, IV-A}} \]
