B. Embryo sac
C. Ovary
D. Egg apparatus.

Answer

To solve the question "Megasporangium is equivalent to," we can follow these steps:

### Step 1: Understand the Term "Megasporangium"
- Megasporangium refers to a structure where megaspores (female spores) are produced. The prefix "mega-" indicates that it is related to the female gametophyte development.

### Step 2: Identify the Options
- The options provided are:
1. Ovule
2. Ambrosec
3. Ovarian
4. Ag apparatus

### Step 3: Analyze Each Option
- **Option 1: Ovule** - The ovule is indeed the structure that contains the megasporangium. It is where the female gametophyte develops.

- **Option 2: Ambrosec** - This term refers to the microspore, which is not equivalent to the megasporangium. Instead, it is the male counterpart.

- **Option 3: Ovarian** - The ovary is the part of the flower that contains the ovules. While it is related, it is not equivalent to the megasporangium itself.

- **Option 4: Ag apparatus** - This is a part of the male gametophyte (related to pollen), and it does not correspond to the megasporangium.

### Step 4: Conclusion
- After analyzing the options, we can conclude that the correct answer is **Option 1: Ovule**, as it is the structure that contains the megasporangium.

### Final Answer
- Megasporangium is equivalent to **Ovule**.
