D. Moss body is gametophyte which consists of two stages namely protonema stage and leafy stage

Explanation

To solve the question "Pick out the Wrong statement," we will analyze each of the four statements provided and determine which one is incorrect.

### Step-by-Step Solution:

1. **Analyze Statement 1**: "Double fertilization is unique to Gymnosperms and Monocotylids."
- **Explanation**: Double fertilization is a process that occurs in angiosperms (flowering plants), not gymnosperms. Gymnosperms do not undergo double fertilization; they produce naked seeds. Therefore, this statement is incorrect.

2. **Analyze Statement 2**: "Sequoia as Gymnosperm is one of the tallest trees."
- **Explanation**: This statement is correct. Sequoias are indeed one of the tallest trees and belong to the gymnosperm group.

3. **Analyze Statement 3**: "Pheophyceae member possesses chlorophyll-C, carotenoids, and xanthophyll."
- **Explanation**: This statement is also correct. Pheophyceae, or brown algae, contain chlorophyll-A and C, along with carotenoids and xanthophyll.

4. **Analyze Statement 4**: "Moss body is gametophytic which consists of two stages namely protanema stage and leafy stages."
- **Explanation**: This statement is correct as well. Mosses, which are bryophytes, have a dominant gametophytic stage that includes the protonema stage and the leafy stage.

### Conclusion:
After analyzing all four statements, we find that the first statement is the only incorrect one. Therefore, the answer to the question is:

**The wrong statement is Statement 1.**
