Question

Which of the following is a water-in-oil type of emulsion?

• A. Milk
• B. Vanishing Cream
• C. Paint
• D. Butter

Hint:

In a W/O emulsion, water droplets are spread in oil, like butter.

Answer 1

The Correct Option is D

Step 1: Idea:
The continuous phase decides the type. We need oil to be the continuous phase.

Step 2: Result:
Butter, cold cream and cod liver oil are the usual W/O examples. Milk and vanishing cream have water as the continuous phase.

Final Answer:
Butter is a water-in-oil emulsion, option (D). \[ \boxed{\text{Butter}} \]
