Concept:
Sprint start mechanics involve proper body positioning and force application to achieve maximum acceleration. According to Newton's Third Law of Motion, when the sprinter pushes against the starting blocks, an equal and opposite reaction propels the body forward.
Step 1: Identify the initial body position.
The sprint start begins with:
\[
\text{Fine point body's contact with ground}
\]
to establish balance and stability.
Step 2: Understand the starting posture.
Next, the sprinter assumes the set position with:
\[
\text{Hip raised}
\]
Step 3: Follow the force application sequence.
The athlete then:
\[
\text{Pushes the block}
\]
which produces:
\[
\text{Opposite reaction}
\]
resulting in:
\[
\text{Gain in momentum}
\]
Thus, the correct sequence is:
\[
B, A, D, C, E
\]
Hence, the correct answer is:
\[
\boxed{(B)\ B, A, D, C, E}
\]
