3. **Analyzing the Options**:
- Option 1: Engler and Prandtl - This is correct as they developed the phylogenetic classification system.
- Option 2: Pliny - He used an artificial system of classification, which is not phylogenetic.
- Option 3: John Ray - He is known for describing species as a unit of classification but did not propose the phylogenetic system.
- Option 4: R. H. Whittaker - He proposed the five-kingdom system of classification, which is different from the phylogenetic system.

4. **Conclusion**:
- Based on the analysis of the options, the correct answer to the question "Phylogenetic system was given by" is **Engler and Prandtl**.
