Step 1: Identify the closing step.
The last action must be confirming the choice in the Paste Special box with OK. That is (B), so (B) belongs at the end. Option 2 has (B) first and option 4 has it second, so both fail.
Step 2: Identify the opening step.
Something has to be selected before any command works. Selecting the formula cell is (C). Option 3 begins with (A), copying with nothing selected, so it fails.
Step 3: Order the middle.
Once the cell is selected, we copy it (A) and only then open Paste Special (D), because paste needs copied content.
Step 4: Write the sequence.
C, then A, then D, then B.
\[ \boxed{\text{(C), (A), (D), (B)}} \]
Final Answer:
Sequence: select the cell, copy, open Paste Special, choose Values and OK (option 1).
