The correct Answer is:
To determine which two statements are correct, let's analyze each statement step by step: ### Step 1: Analyze Statement (i) - **Statement (i)**: BCG is a triple vaccine, effective against tuberculosis, typhoid, and malaria. - **Analysis**: The BCG vaccine is specifically used to protect against tuberculosis (TB) only. It is not effective against typhoid or malaria. Therefore, this statement is **incorrect**. ### Step 2: Analyze Statement (ii) - **Statement (ii)**: Malaria is transmitted by both male and female Anopheles mosquitoes. - **Analysis**: Malaria is transmitted only by female Anopheles mosquitoes. Male Anopheles do not bite and therefore do not transmit malaria. Hence, this statement is also **incorrect**. ### Step 3: Analyze Statement (iii) - **Statement (iii)**: Chronic diseases are characterized by drastic long-term effects. - **Analysis**: Chronic diseases are indeed characterized by long-term effects, often lasting for months or years. This statement is **correct**. ### Step 4: Analyze Statement (iv) - **Statement (iv)**: Addison's disease is caused due to hyposecretion of aldosterone. - **Analysis**: Addison's disease is caused by the insufficient production of hormones, including aldosterone, from the adrenal glands. Therefore, this statement is **correct**. ### Conclusion Based on the analysis: - The correct statements are (iii) and (iv). ### Final Answer The two correct statements are: - (iii) Chronic diseases are characterized by drastic long-term effects. - (iv) Addison's disease is caused due to hyposecretion of aldosterone. ---
