Assertion : Geneecology is the study of genetic composition and changes in relation to the origin of ecades , ecotypes , new sps. , etc .
Reason: Autecology deals with the study of a group of organisms .

Options

A. If both Assertion and Reason are true and Reason is 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 and false.

Answer

To solve the assertion-reason question, we will analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "Geneecology is the study of genetic composition and changes in relation to the origin of ecades, ecotypes, new species, etc."

- **Evaluation**: This statement is true. Geneecology indeed focuses on the genetic aspects of organisms in relation to their ecological contexts, including the study of how genetic composition changes with the emergence of new species and ecotypes.

### Step 2: Analyze the Reason
The reason states that "Autecology deals with the study of a group of organisms."

- **Evaluation**: This statement is false. Autecology is actually the study of individual species and their interactions with the environment, rather than a group of organisms. It focuses on how a single species interacts with both biotic (living) and abiotic (non-living) factors in its environment.

### Step 3: Conclusion
Based on the evaluations:
- The assertion is true.
- The reason is false.

Thus, the correct conclusion is that the assertion is true, but the reason is false.

### Final Answer
The correct option is: Assertion is true, Reason is false.
