Answer

To solve the question regarding the insectivorous plant with a rosette of spiny margined bilobed hinged and winged leaves for catching prey, we can analyze the options provided:

1. **Nephenthes**: This plant is commonly known as the pitcher plant. Its structure consists of a pitcher-shaped leaf that traps insects, but it does not have the described characteristics of being rosetted, spiny margined, bilobed, hinged, and winged. Therefore, this option is incorrect.

2. **Drosera**: Known as sundews, these plants have tentacle-like structures on their leaves that secrete a sticky substance to trap insects. However, they do not fit the description of having spiny margined, bilobed, hinged, and winged leaves. Thus, this option is also incorrect.

3. **Dionaea**: Commonly known as the Venus flytrap, this plant has a unique structure where the leaf is modified into a trap that is bilobed with hinged lobes. The lobes have spiny margins and can snap shut to catch prey. This matches the description given in the question, making this option the correct answer.

4. **Petrichlorium**: This plant is less commonly known and does not fit the description provided in the question. It does not have the specific characteristics mentioned, making it an incorrect option.

After evaluating all the options, the correct answer is **C) Dionaea (Venus flytrap)**.

### Step-by-Step Solution:
1. **Identify the characteristics**: Look for the specific features mentioned in the question: rosette, spiny margined, bilobed, hinged, and winged leaves.
2. **Analyze each option**: Review each plant option to see if they match the characteristics.
3. **Eliminate incorrect options**: Rule out Nephenthes and Drosera based on their structures not matching the description.
4. **Confirm the correct option**: Recognize that Dionaea fits all the criteria provided in the question.
5. **Conclude with the answer**: State that the correct answer is Dionaea (Venus flytrap).
