Concept:
Homo erectus is an important extinct human ancestor known for:
• Upright posture,
• Increased cranial capacity,
• Use of tools,
• Wide geographical distribution.
Several famous fossil discoveries are associated with different hominin species.
Step 1: Analyzing Peking Man.
Peking Man fossils were discovered in:
\[
\text{Zhoukoudian, China}
\]
These fossils are classified as:
\[
\boxed{\textit{Homo erectus}}
\]
Therefore:
\[
A = \textit{Homo erectus}
\]
Hence it should not be included among the incorrect options.
Step 2: Analyzing Lucy.
Lucy is one of the most famous fossil discoveries belonging to:
\[
\textit{Australopithecus afarensis}
\]
Lucy is not classified as:
\[
\textit{Homo erectus}
\]
Thus:
\[
B = \text{Not Homo erectus}
\]
Step 3: Analyzing Taung Child.
Taung Child belongs to:
\[
\textit{Australopithecus africanus}
\]
It was discovered in South Africa and represents an early australopithecine fossil.
Therefore:
\[
C = \text{Not Homo erectus}
\]
Step 4: Analyzing Black Skull.
Black Skull refers to:
\[
\textit{Paranthropus aethiopicus}
\]
This robust australopithecine fossil is not a member of:
\[
\textit{Homo erectus}
\]
Thus:
\[
D = \text{Not Homo erectus}
\]
Step 5: Writing the correct combination.
The fossils which are not Homo erectus are:
\[
B,\; C,\; D
\]
Hence, the correct answer is:
\[
\boxed{\text{(A) B, C and D only}}
\]
