Viroids are small infectious particles which are devoid of :
`I.` Capsomeres `II`. Enzymes
`III`. Ribonucleic acid `IV` DNA

Options

A. `I,II` and `III`
B. `I,III` and `IV`
C. `I,II` and IV`
D. `II, III` and `IV`

Answer

To solve the question regarding viroids and what they are devoid of, we can follow these steps:

### Step 1: Understand what viroids are
Viroids are small infectious agents that are smaller than viruses. They are known to cause diseases in plants, such as the Potato Spindle Tuber Disease.

### Step 2: Identify the components of viroids
Viroids consist of a short strand of circular RNA and do not have a protein coat, which is typically found in viruses.

### Step 3: Analyze the options given in the question
- **I. Capsomeres**: Viroids do not have capsomeres because they lack a protein coat.
- **II. Enzymes**: Viroids do not have enzymes, which are typically present in viruses.
- **III. Ribonucleic acid**: This is incorrect because viroids do contain ribonucleic acid (RNA).
- **IV. DNA**: Viroids do not have DNA; they are solely made up of RNA.

### Step 4: Conclude which options are correct
From the analysis:
- Viroids are devoid of **capsomeres** (I), **enzymes** (II), and **DNA** (IV).
- They do contain **ribonucleic acid** (III), so this option is incorrect.

### Final Answer
Viroids are devoid of:
- I. Capsomeres
- II. Enzymes
- IV. DNA

Thus, the correct answer is options I, II, and IV.
