Assertion : Java Ape-man, Peking man and Heidelberg man are the fossils of Homo erectus.
Reason : Homo erectus evolved from Homo habilis.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Explanation

To solve the question regarding the assertion and reason about Homo erectus, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states that "Java Ape-man, Peking man, and Heidelberg man are the fossils of Homo erectus."

- **Fact Check**:
- The Java Ape-man (Homo erectus) was discovered in Central Java, Indonesia, and dates back to the Pleistocene epoch.
- The Peking man (Homo erectus) was found in Zhoukoudian, China, also dating to the Pleistocene.
- The Heidelberg man (Homo heidelbergensis) is often classified under Homo erectus as well, with fossils found in Europe.

**Conclusion**: The assertion is true.

### Step 2: Analyze the Reason
The reason states that "Homo erectus evolved from Homo habilis."

- **Fact Check**:
- Homo habilis is considered one of the earliest members of the genus Homo and is believed to have lived approximately 2.4 to 1.4 million years ago.
- Homo erectus is believed to have evolved from Homo habilis, appearing around 1.7 million years ago.

**Conclusion**: The reason is also true.

### Step 3: Determine the Relationship
Now we need to determine if the reason is the correct explanation for the assertion.

- The assertion identifies specific fossils that belong to Homo erectus.
- The reason explains the evolutionary lineage from Homo habilis to Homo erectus.

**Conclusion**: While both statements are true, the reason does not specifically explain why the Java Ape-man, Peking man, and Heidelberg man are classified as Homo erectus.

### Final Answer
Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion. Therefore, the correct answer is option B: "Both assertion and reason are true, but reason is not the correct explanation of assertion."
