The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that muscles have special features such as excitability, conductivity, and contractibility. - **Explanation**: Muscle tissues, including skeletal, cardiac, and smooth muscles, indeed possess these characteristics. Excitability allows muscles to respond to stimuli, conductivity enables the transmission of electrical impulses, and contractibility refers to the ability of muscle fibers to shorten and generate force. 2. **Analyzing the Reason**: The reason provided claims that neurons have the same type of characteristics that are found in muscles. - **Explanation**: Neurons are specialized cells of the nervous system that are responsible for transmitting nerve impulses. While neurons do exhibit excitability and conductivity, they do not possess contractibility, which is a unique feature of muscle cells. 3. **Evaluating the Truth of Assertion and Reason**: - The assertion is **true** because muscles do have excitability, conductivity, and contractibility. - The reason is **false** because, although neurons share some characteristics with muscle cells (like excitability and conductivity), they do not have the characteristic of contractibility. 4. **Conclusion**: Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is false. ### Final Answer: - The assertion is true, and the reason is false.
