Assertion : Receptors are crucial to body's communicational process.
Reason : Receptors are proteins.

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

**Step-by-Step Text Solution:**

1. **Understanding the Assertion**: The assertion states that "Receptors are crucial to the body's communicational process." This means that receptors play a vital role in how cells communicate with each other. They are involved in receiving signals from neurotransmitters and other signaling molecules.

2. **Understanding the Reason**: The reason given is "Receptors are proteins." This indicates that receptors are made up of proteins, which are essential biological molecules that perform a variety of functions in living organisms, including acting as receptors.

3. **Analyzing the Relationship**: To determine if the reason supports the assertion, we need to consider whether the fact that receptors are proteins explains why they are crucial to communication. While it is true that receptors are proteins, the assertion focuses on their role in communication, not their composition.

4. **Conclusion**: The assertion is true because receptors are indeed crucial for communication within the body. The reason is also true because receptors are proteins. However, the reason does not adequately explain the assertion. Therefore, while both statements are correct, the reason does not support the assertion.

5. **Final Answer**: The correct answer is that the assertion is true, the reason is true, but the reason does not explain the assertion.
