Read the following statement carefully "Further development of zygote depends on the type of life cycle the organism has the enviroment it exposed to"
Identify the correctly matched pair w.r.t the above statement.

Options

A. Thick walled zygote - Haplontic life cycle
B. Zygote forms new generation by mitosis represted by few cells - Haplodiplontic life cycle
C. Zygote undergoes meiosis to form haploid generation - Diplontic life cycle
D. Aygote forms multicellular diploid generation - Haplontic life cycle.

Answer

To solve the question, we need to identify the correctly matched pair concerning the statement: "Further development of zygote depends on the type of life cycle the organism has and the environment it is exposed to."

### Step-by-Step Solution:

1. **Understanding Life Cycles**:
- Organisms can have different types of life cycles: haplontic, diplontic, and haplodiplontic.
- In a haplontic life cycle, the dominant stage is the haploid gametophyte, while in a diplontic life cycle, the dominant stage is the diploid sporophyte. The haplodiplontic life cycle includes both stages.

2. **Analyzing the Statements**:
- **Statement A**: Thick-walled zygote in a haplontic life cycle.
- In a haplontic cycle, the zygote is typically short-lived and quickly undergoes meiosis to produce haploid spores. The presence of a thick-walled zygote does not correlate directly with the life cycle type.
- **Statement B**: The zygote forms a new generation by mitosis in a haplodiplontic life cycle.
- This is accurate because in a haplodiplontic life cycle, the zygote (2n) undergoes mitosis to develop into a multicellular sporophyte (also 2n).
- **Statement C**: The zygote undergoes meiosis to form a haploid generation in a diplontic life cycle.
- This is incorrect because in a diplontic life cycle, the zygote remains diploid and does not undergo meiosis until it forms spores.
- **Statement D**: A zygote forms a multicellular diploid generation in a haplontic life cycle.
- This is incorrect as well; in a haplontic life cycle, the zygote does not develop into a multicellular diploid organism but rather quickly undergoes meiosis.

3. **Identifying the Correct Statement**:
- After analyzing all statements, **Statement B** is the only one that correctly matches the context of the original statement regarding the development of the zygote.

### Final Answer:
The correctly matched pair with respect to the statement is **Statement B**: "The zygote forms a new generation by mitosis in a haplodiplontic life cycle."
