1)PCR
2) agitator
3) bioreactor
4) assimilator

Options

A. 1)PCR
B. 2) agitator
C. 3) bioreactor
D. 4) assimilator

Answer

To solve the question "A device in which large volume of living cells are cultured in order to get a specific product is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for a specific device used for culturing living cells in large volumes to produce a particular product.

2. **Analyze the Options**:
- **Option 1: PCR** - This stands for Polymerase Chain Reaction, which is a technique used for amplifying DNA, not for culturing cells. Therefore, this option is incorrect.
- **Option 2: Agitator** - An agitator is a device used to stir liquids. It does not refer to a device specifically designed for culturing cells. Thus, this option is also incorrect.
- **Option 3: Bioreactor** - A bioreactor is a large vessel where living cells are cultured under controlled conditions to produce specific products, such as proteins or metabolites. This option fits the description given in the question.
- **Option 4: Assimilator** - This term does not refer to a device used for culturing cells and is therefore incorrect.

3. **Select the Correct Option**: Based on the analysis, the correct answer is **Option 3: Bioreactor**.

### Final Answer:
The device in which large volumes of living cells are cultured to obtain a specific product is called a **bioreactor**.
