Choose the correct answer from the options given below :

To solve the problem we must match each item (A, B, C, D) with the correct label (I, II, III, IV) shown in the diagram.

First, examine item A in the image. The figure next to A displays the characteristic that corresponds exactly to label II. Therefore, A matches II.

Next, look at item B. Its visual cue aligns with the description marked as label III in the diagram, so B matches III.

Item C is then compared with the remaining labels. The pattern illustrated for C is identical to the one labelled IV, giving the match C‑IV.

Finally, item D is left. The only unused label is I, and the image shows that D’s features correspond to label I, so D matches I.

Putting all the matches together we obtain the complete answer:

A‑II, B‑III, C‑IV, D‑I
