Options

A. O,P, minerals
B. H,C, Iron

D. O,C,H,N.

Answer

To answer the question "Protoplasm is formed of," we can follow these steps:

### Step 1: Understand Protoplasm
Protoplasm is the living substance within a cell, which includes both the cytoplasm and nucleoplasm.

### Step 2: Identify Components of Protoplasm
Protoplasm consists of two main parts:
- **Cytoplasm**: The fluid that fills the cell outside the nucleus.
- **Nucleoplasm**: The fluid that fills the nucleus.

### Step 3: Determine the Composition of Cytoplasm and Nucleoplasm
Both cytoplasm and nucleoplasm are primarily composed of:
- **Proteins**
- **Water**
- Various ions and organic molecules.

### Step 4: Focus on the Main Elements in Proteins
The proteins found in protoplasm are made up of several elements. The most significant elements that make up proteins are:
- **Carbon (C)**
- **Hydrogen (H)**
- **Oxygen (O)**
- **Nitrogen (N)**

### Step 5: Conclude the Composition of Protoplasm
Based on the above information, we can conclude that protoplasm is primarily formed of:
- **Oxygen (O)**
- **Carbon (C)**
- **Hydrogen (H)**
- **Nitrogen (N)**

Thus, the final answer is that protoplasm is formed of **oxygen, carbon, hydrogen, and nitrogen**.
