Mark the correct sequence for the separation of mixture of iron filings, sand and sugar.

Options

A. Sedimentation and filtration `to` Use of magnet `to` Evaporation
B. Use of magnet `to` Sedimentation and filtration `to` Evaporation
C. Use of magnet `to` Evaporation ` to` Filtration and decantation
D. Filtration `to` Use of magnet `too` Sedimentation and decantation

Explanation

To separate a mixture of iron filings, sand, and sugar, we can follow these steps:

### Step 1: Use a Magnet to Remove Iron Filings
- **Explanation**: Iron filings are magnetic, so we can use a magnet to attract and remove them from the mixture.
- **Result**: After this step, we are left with a mixture of sand and sugar.

### Step 2: Add Water to the Mixture
- **Explanation**: When we add water to the remaining mixture of sand and sugar, the sugar will dissolve in the water, while the sand will not.
- **Result**: We now have a solution of sugar in water and undissolved sand at the bottom.

### Step 3: Sedimentation
- **Explanation**: The sand, being insoluble, will settle down at the bottom of the container due to gravity. This process is called sedimentation.
- **Result**: We have separated the sand from the sugar solution.

### Step 4: Filtration
- **Explanation**: We can now filter the mixture to separate the dissolved sugar from the sand. The sugar solution will pass through the filter paper, while the sand will remain on the filter paper.
- **Result**: We obtain a filtrate that contains sugar dissolved in water.

### Step 5: Evaporation
- **Explanation**: To recover the sugar from the sugar solution, we can heat the solution to evaporate the water. As the water evaporates, sugar will crystallize and remain.
- **Result**: We are left with sugar crystals after the evaporation process.

### Final Sequence
1. Use a magnet to remove iron filings.
2. Add water to the mixture.
3. Allow sedimentation to occur.
4. Filter the mixture to separate sand from the sugar solution.
5. Evaporate the water to obtain sugar.
