The type of chromatography where the stationary phase is held in a narrow tube is c. Column Chromatography.

Here's a step-by-step explanation:

1. In chromatography, there are two phases: the stationary phase and the mobile phase. The stationary phase is the phase that doesn't move, and the mobile phase is the phase that moves through the stationary phase.

2. In Column Chromatography, the stationary phase is held inside a narrow tube (the column). The mobile phase moves through this column.

3. As the mobile phase moves through the column, different components of the mixture being analyzed move at different rates, leading to their separation.

4. Liquid Chromatography, Paper Chromatography, and Thin Layer Chromatography also involve a stationary phase and a mobile phase, but the setup is different. For example, in Paper Chromatography, the stationary phase is a piece of special paper, and in Thin Layer Chromatography, it's a thin layer of material (like silica gel) on a plate.

So, your choice, c. Column Chromatography, is correct.

The type of chromatography where the stationary phase is held in a narrow tube is c. Column Chromatography.

Here's a step-by-step explanation:

1. In chromatography, there are two phases: the stationary phase and the mobile phase. The stationary phase does not move and the mobile phase flows through it.

2. In Column Chromatography, the stationary phase is held inside a narrow tube (the column). The mobile phase (a liquid or a gas) is then passed through the column.

3. The different components in the sample mixture interact differently with the stationary phase, causing them to move at different speeds and separate from each other.

4. This method is commonly used in the purification of liquids or gases because it can effectively separate the components based on their interaction with the stationary phase.

So, your choice, c. Column Chromatography, is correct.
