The correct Answer is:
To solve the question, we need to identify the correct hormones corresponding to the blanks A, B, and C in the provided table. Let's analyze each blank step by step. ### Step 1: Identify the hormone for Blank A - The hormone given is **Oestrogen**. - Oestrogen is primarily produced in the **ovaries** and is responsible for the **maintenance of secondary sexual characters** in females. - Therefore, the correct entry for Blank A is **Oestrogen** from the **Ovary**. ### Step 2: Identify the hormone for Blank B - The source gland mentioned is **Alpha cells of Islets of Langerhans**. - These alpha cells secrete a hormone called **Glucagon**. - The major effect of Glucagon is to **raise blood sugar levels**. - Thus, the correct entry for Blank B is **Glucagon** from the **Alpha cells of Islets of Langerhans**. ### Step 3: Identify the hormone for Blank C - The source gland mentioned is the **Anterior Pituitary**. - The hormone secreted by the anterior pituitary that is relevant here is the **Growth Hormone (GH)**. - Over secretion of Growth Hormone leads to a condition known as **Gigantism**. - Therefore, the correct entry for Blank C is **Growth Hormone** from the **Anterior Pituitary**. ### Summary of the Answers - A: Oestrogen (from Ovary) - B: Glucagon (from Alpha cells of Islets of Langerhans) - C: Growth Hormone (from Anterior Pituitary) ### Final Answer The correct option for the three blanks A, B, and C is: - A: Oestrogen - B: Glucagon - C: Growth Hormone
