Which of the following shows syngamy and triple fusion ?

Options

A. Gymnosperms
B. Algae
C. Fungi
D. Angiosperms

Explanation

To solve the question "Which of the following shows syngamy and triple fusion?", we can follow these steps:

### Step 1: Understand the Terms
- **Syngamy**: This is the fusion of male and female gametes, resulting in the formation of a zygote.
- **Triple Fusion**: This involves the fusion of a second male gamete with two polar nuclei in the embryo sac, resulting in the formation of a triploid cell, which develops into the endosperm.

### Step 2: Identify the Process
- The combination of syngamy and triple fusion is known as **double fertilization**. This process is a unique characteristic of angiosperms (flowering plants).

### Step 3: Analyze the Options
- We need to look at the options provided (though they are not listed here, we know the common groups):
- **Angiosperms**: Known for double fertilization (syngamy and triple fusion).
- **Gymnosperms**: Do not exhibit triple fusion.
- **Algae**: Generally do not show triple fusion.
- **Fungi**: Do not exhibit these processes.

### Step 4: Conclusion
- Based on the analysis, the only group that shows both syngamy and triple fusion is **angiosperms**. Therefore, the correct answer is **Option 4: Angiosperms**.
