Answer

To solve the question regarding the properties seen in both mango and coconut, let's analyze each statement step by step.

### Step 1: Analyze Property I - The fruit is called a drupe.
- **Explanation:** Both mango and coconut are classified as drupes. A drupe is a type of fruit that has an outer fleshy part surrounding a shell (the pit or stone) with a seed inside.
- **Conclusion:** This property is true for both mango and coconut.

### Step 2: Analyze Property II - The fruit is developed from superior ovaries.
- **Explanation:** In both mango and coconut, the fruit develops from a superior ovary. This means that the ovary is positioned above the other floral parts, which is characteristic of many fruits.
- **Conclusion:** This property is also true for both mango and coconut.

### Step 3: Analyze Property III - The fruit is one-seeded.
- **Explanation:** Both mango and coconut fruits contain a single seed. In mango, the seed is enclosed within the fleshy fruit, and in coconut, the seed is enclosed within the hard shell.
- **Conclusion:** This property is true for both mango and coconut.

### Step 4: Analyze Property IV - The middle layer of the fruit wall is edible.
- **Explanation:** In mango, the middle layer (mesocarp) is fleshy and edible. However, in coconut, the mesocarp is fibrous and not considered edible in the same way. The edible part of the coconut is the inner layer (endocarp) where the coconut meat is found.
- **Conclusion:** This property is not true for both mango and coconut.

### Final Conclusion:
Based on the analysis:
- Properties I, II, and III are common to both mango and coconut.
- Property IV is not common to both.

Thus, the correct answer is:
**Option A: 1, 2, and 3 are common properties for both mango and coconut.**
