Options

A. (i),(ii) and (iii) are correct
B. (i) and (iv) are correct
C. (ii) and (iii) are correct
D. (iii) and (iv) are correct

Answer

**Step-by-Step Solution:**

1. **Understanding Tissue Culture**: Tissue culture is a technique where parts of a plant (such as cells or tissues) are taken from a parent plant and placed in a nutrient medium to grow new plants. This process allows for the propagation of plants under controlled conditions.

**Hint**: Remember that tissue culture involves using parts of a parent plant to grow new plants in a lab setting.

2. **Genetic Uniformity**: The new plants produced through tissue culture are genetically uniform. This means that they have the same genetic makeup as the parent plant because they are derived from the same genetic material. There is no mixing of genes from different plants.

**Hint**: Think about how clones are created; they are exact genetic copies of the original.

3. **Inoculum Usage**: The term "inoculum" refers to the initial material used to start a culture. In the context of tissue culture, the new plants produced are not used as inoculum because they are the result of the culture process, not the starting material.

**Hint**: Inoculum is like the seed or starting point for a culture, not the product of it.

4. **Genetic Similarity**: While tissue culture plants can be genetically similar to the parent plant, they are not always genetically identical if genetic engineering techniques are applied. This means that the statement about them being genetically similar is not always true.

**Hint**: Consider whether genetic modifications can change the genetic similarity of the plants.

5. **Clones**: The new plants produced through tissue culture are referred to as clones. Clones are genetically identical to the parent plant because they originate from the same tissue without any genetic alteration.

**Hint**: Clones are essentially duplicates of the original organism.

6. **Conclusion**: Based on the analysis:
- (i) Genetically uniform - True
- (ii) Used as inoculum - False
- (iii) Genetically similar - Not always true
- (iv) Called clones - True

Therefore, the correct statements about plants raised through tissue culture are (i) and (iv).

**Final Answer**: (i) Genetically uniform and (iv) Called clones are correct.
