Greatest extent of adaptation to various environments is found in
(a) Gymnosperms
(b) Bryophytes
(c) Ferns
(d) Angiosperms

Options

A. Gymnosperms
B. Bryophytes
C. Ferns
D. Angiosperms.

Answer

To determine which group of plants has the greatest extent of adaptation to various environments, we can analyze the options provided:

### Step 1: Understand the Groups
- **Gymnosperms**: These are seed-producing plants that include conifers. They are primarily adapted to dry and cold environments but have limited adaptability compared to angiosperms.
- **Bryophytes**: These are non-vascular plants like mosses and liverworts. They are generally found in moist environments and have limited adaptability to extreme conditions.
- **Ferns**: These are vascular plants that reproduce via spores. They thrive in moist, shaded environments but are not as versatile as angiosperms.
- **Angiosperms**: These are flowering plants that produce seeds enclosed within a fruit. They are found in a wide variety of environments, including deserts, wetlands, and tropical forests.

### Step 2: Analyze Adaptation
- **Gymnosperms**: Adapted mainly to specific environments but less versatile.
- **Bryophytes**: Limited to moist environments; not highly adaptable.
- **Ferns**: Require specific conditions; not as adaptable as angiosperms.
- **Angiosperms**: Exhibit a wide range of adaptations to various climates and habitats, including extreme conditions.

### Step 3: Conclusion
Based on the analysis, angiosperms (option D) have the greatest extent of adaptation to various environments compared to the other groups listed.

### Final Answer
**(d) Angiosperms**
