The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states: "Neurons protect and support the neuroglial cells." - Neurons are the primary cells responsible for transmitting nerve impulses and are not known for protecting or supporting neuroglial cells. Instead, neuroglial cells (or glial cells) support and protect neurons. Therefore, this assertion is **false**. ### Step 2: Analyze the Reason The reason states: "Neuroglial cells make up ninety percent of neural tissue in our body." - While neuroglial cells do comprise a significant portion of the brain's cellular makeup, the claim that they make up 90% of neural tissue is incorrect. It is estimated that neuroglial cells make up about 50% of the total brain cells. Therefore, this reason is also **false**. ### Step 3: Conclusion Since both the assertion and the reason are false, the correct answer to the question is that both the assertion and the reason are false. ### Final Answer: Both assertion and reason are false. ---
