Concept:
Prehistoric stone tool technology evolved gradually from primitive techniques to highly sophisticated methods. Different tool-making techniques belong to different cultural phases of prehistory.
To arrange them correctly, we must understand:
• Which technique appeared earliest,
• Which technique developed later,
• The chronological evolution of lithic technology.
Step 1: Understanding Block-on-Block Technique.
The Block-on-Block technique is one of the earliest and simplest methods of stone tool production.
In this technique:
• One stone block is struck against another,
• Large crude flakes are produced,
• Tool manufacture remains primitive.
This technique belongs to the earliest stages of stone tool technology.
Therefore:
\[
D = \text{Earliest}
\]
Step 2: Understanding Clactonian flaking.
Clactonian flaking belongs to the Lower Paleolithic cultural tradition.
It represents:
• More systematic flake production,
• Use of striking platforms,
• Development beyond crude pebble technology.
Thus, it developed after primitive block-on-block techniques.
Therefore:
\[
C = \text{After D}
\]
Step 3: Understanding Pressure Flaking Technique.
Pressure flaking is a more advanced lithic technique in which:
• Small flakes are removed using pressure rather than direct blows,
• Greater precision and refinement are achieved,
• Sophisticated blade tools are produced.
This technique emerged later in prehistoric cultural development.
Thus:
\[
B = \text{After C}
\]
Step 4: Understanding Fluting Technique.
Fluting technique is highly specialized and advanced.
It is associated with:
• Carefully shaped projectile points,
• Sophisticated stone craftsmanship,
• Advanced prehistoric technological stages.
Therefore:
\[
A = \text{Latest}
\]
Step 5: Arranging the sequence chronologically.
The correct chronological order from earliest onwards becomes:
\[
D \rightarrow C \rightarrow B \rightarrow A
\]
Thus:
\[
\boxed{\text{D-C-B-A}}
\]
Hence, the correct answer is:
\[
\boxed{\text{(B) D-C-B-A}}
\]
