Assertion: The endocrine part of human pancreas is represented by `alpha` and `beta` cells.
Reason: Endocrine gland have ducts.

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 question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states: "The endocrine part of human pancreas is represented by alpha and beta cells."

- The pancreas has two main functions: an exocrine function (which involves the secretion of digestive enzymes) and an endocrine function (which involves the secretion of hormones).
- The endocrine part of the pancreas consists of clusters of cells known as the islets of Langerhans, which contain alpha cells and beta cells.
- Alpha cells produce glucagon, while beta cells produce insulin, both of which are hormones that regulate blood sugar levels.

**Conclusion for Step 1:** The assertion is true.

### Step 2: Analyze the Reason
The reason states: "Endocrine glands have ducts."

- Endocrine glands are characterized as ductless glands. They do not have ducts and release hormones directly into the bloodstream.
- In contrast, exocrine glands do have ducts and secrete their products (like enzymes) through these ducts to specific sites.

**Conclusion for Step 2:** The reason is false.

### Step 3: Combine the Conclusions
- The assertion is true, and the reason is false. Therefore, the correct relationship between the assertion and reason is that the assertion is true, but the reason is false.

### Final Answer
The correct answer is that the assertion is true, and the reason is false.
