The correct Answer is:
To solve the question, we need to fill in the blanks in the three statements provided. Let's analyze each statement step by step. ### Step 1: Analyze Statement A **Statement A:** Each seminiferous tubule is lined on its inside by two types of cells called `overset(i)"______"` and `overset(ii)"______"`. - The two types of cells that line the seminiferous tubules are: 1. **Sertoli cells** (which support and nourish the developing sperm) 2. **Leydig cells** (which produce testosterone) So, the correct fill-ins for Statement A are: - (i) Sertoli cells - (ii) Leydig cells ### Step 2: Analyze Statement B **Statement B:** The seminiferous tubules open into the `overset(i)"______"` through `overset(ii)"______"`. - The seminiferous tubules open into: 1. **Rete testis** (a network of tubules) 2. **Vasa efferentia** (which transport sperm from the rete testis to the epididymis) So, the correct fill-ins for Statement B are: - (i) Rete testis - (ii) Vasa efferentia ### Step 3: Analyze Statement C **Statement C:** The enlarged end of the penis called the `overset(i)"______"` is covered by a loose fold of skin called the `overset(ii)"______"`. - The enlarged end of the penis is called: 1. **Glans penis** - The loose fold of skin covering it is called: 2. **Foreskin** (or prepuce) So, the correct fill-ins for Statement C are: - (i) Glans penis - (ii) Foreskin ### Conclusion From the analysis, we can summarize the correct answers for any two statements as follows: - For Statement A: Sertoli cells and Leydig cells - For Statement B: Rete testis and Vasa efferentia - For Statement C: Glans penis and Foreskin The correct option that fills the blanks in any two statements is: - **Option 2** (which corresponds to Statement B and Statement C).
