C. Endosperm, Nucellus, Synergids
D. Antipodal, Synergids & lnteguments

Answer

To solve the question regarding the haploid, diploid, and triploid conditions in flowering plants, we can break down the information step by step:

### Step 1: Understand the Terms
- **Haploid (N)**: A cell or organism that has one set of chromosomes.
- **Diploid (2N)**: A cell or organism that has two sets of chromosomes.
- **Triploid (3N)**: A cell or organism that has three sets of chromosomes.

### Step 2: Identify the Structures
In flowering plants, we can identify the following structures that correspond to these conditions:
- **Haploid Structures**: These include the gametes (like the egg cell) and other parts of the gametophyte generation.
- **Diploid Structures**: These include the sporophyte generation, such as the nucellus (the tissue surrounding the ovule).
- **Triploid Structures**: This condition is typically found in the endosperm, which is formed during fertilization.

### Step 3: Analyze the Formation of Endosperm
- The endosperm is formed through a process called triple fusion, where one male gamete fuses with two polar nuclei in the central cell of the ovule. This results in a triploid (3N) endosperm.

### Step 4: Summarize the Findings
- **Haploid**: Egg (female gamete) - N
- **Diploid**: Nucellus (part of the ovule) - 2N
- **Triploid**: Endosperm (nutritive tissue for the developing embryo) - 3N

### Conclusion
Based on the analysis, we can conclude that the haploid, diploid, and triploid conditions can be traced in the following:
- **Haploid**: Egg (N)
- **Diploid**: Nucellus (2N)
- **Triploid**: Endosperm (3N)

Thus, the correct answer to the question is option number 1.
