Assertion: The term biology ws coined by Lamarck and Travernis.
Reason: Morphology deals with the external form and structure of organisms.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the assertion and reason question, we need to analyze both the assertion and the reason separately and determine their correctness and relationship.

### Step 1: Analyze the Assertion
The assertion states: "The term biology was coined by Lamarck and Travernis."

- **Explanation**: The term "biology" indeed refers to the branch of science that studies living organisms. It was coined by Jean-Baptiste Lamarck and Pierre Tremblay (often referred to as Travernis) in the early 19th century. They both contributed to the definition and understanding of biology through their studies of life forms and the conditions in which these life forms exist.

**Conclusion**: The assertion is **correct**.

### Step 2: Analyze the Reason
The reason states: "Morphology deals with the external form and structure of organisms."

- **Explanation**: Morphology is a branch of biology that focuses on the form and structure of organisms, including their external characteristics. It encompasses various aspects of the physical form of plants and animals. This definition aligns with the accepted understanding of morphology in biological sciences.

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

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

- While both the assertion and reason are correct, the reason does not explain why Lamarck and Travernis coined the term "biology." The assertion is about the origin of the term, while the reason discusses a specific branch of biology (morphology) without connecting it to the coining of the term.

**Conclusion**: The reason is **not the correct explanation** for the assertion.

### Final Answer
Both the assertion and reason are correct, but the reason is not the correct explanation of the assertion.
