Step 1: Start with the easiest pair.
The word banner suggests something stretched wide like a flag. A banner headline runs across many columns. So A goes with II.
Step 2: Use the options to narrow down.
A is II in option 2 only. Options 1, 3 and 4 give A as I or III. So only option 2 survives if A-II is correct.
Step 3: Confirm B.
A boxed headline is enclosed in a box, so it appears in a small rectangle shape. B goes with IV. Option 2 also has B-IV.
Step 4: Confirm C.
A jumphead means the story jumps to another page, and the head there is a secondary head. C goes with I. Option 2 has C-I.
Step 5: Confirm D.
A crosshead breaks a long column with a small centred heading. D goes with III. Option 2 has D-III.
Step 6: Why the other options fail.
Option 1 puts A with I, but I describes a jump head, not a banner. Option 3 gives D-III but also A-I, so it fails. Option 4 gives A-III, but a banner is not centred on one column.
Step 7: Memory aid.
Quick recap of the memory aids: banner means wide, boxed means a box, jumphead means the story jumps, and crosshead sits across the middle of a column text. Each aid points to the same pairs as option 2, so there is no second possible match.
Final Answer:
All four pairs agree with option 2.
\[ \boxed{2} \]
