Cycas is living fossil as it has

Options

A. Ciliated sperms
B. Structure like that of Tree Fern
C. Restricted occurrence in certain areas
D. Been found in fossil state also.

Explanation

### Step-by-Step Solution:

1. **Understanding the Term "Living Fossil":**
- A living fossil is an organism that has no close living relatives and whose relatives are known only from the fossil record. This means that the organism has survived for millions of years with little change.

2. **Characteristics of Cycas:**
- Cycas belongs to the family Cycadaceae and is considered a living fossil due to its ancient lineage and unique characteristics that have persisted over time.

3. **Analyzing the Options:**
- **Option 1: Ciliated Sperm** - While Cycas does have ciliated sperm, this characteristic alone does not define it as a living fossil.
- **Option 2: Structure like that of Tree Fern** - This is also not a defining characteristic of being a living fossil.
- **Option 3: Restricted Occurrence in Certain Areas** - This is a key characteristic of living fossils. Cycas species have a limited geographical distribution and are often found in specific regions, making them vulnerable to extinction.
- **Option 4: Being Found in the Fossil State Also** - While Cycas has ancient relatives found in the fossil record, this does not solely qualify it as a living fossil.

4. **Conclusion:**
- The correct answer is **Option 3: Restricted occurrence in certain areas**. This characteristic highlights why Cycas is classified as a living fossil, as it reflects its limited distribution and the threat of extinction.
