All the following are properties of an indifference curves except

Step 1: Analyze the question We need the option that is NOT a property of indifference curves ("except").

Step 2: The concept An indifference curve shows combinations of two goods that give a consumer the same level of satisfaction. Its standard properties are:

1. It slopes downward from left to right (more of one good means less of the other to stay equally satisfied).
2. It is convex to the origin (diminishing marginal rate of substitution).
3. Curves higher up and to the right represent higher levels of satisfaction.
4. Two indifference curves never intersect.

Step 3: Check each option

• A. It can intersect - This is false. If two curves crossed, the point of intersection would give the same satisfaction on both curves, which would mean the two curves represent the same level of satisfaction. That contradicts the idea that different curves show different levels. So this is NOT a property.
• B. It slopes downward from left to right - True. It has a negative slope, like a normal demand curve.
• C. Shifting rightward shows higher satisfaction - True.
• D. It does not intersect - True.

Step 4: Answer The option that is not a property of indifference curves is A.

Tip: In "except" questions, find the false statement. Remember that indifference curves never cross, so any option saying they "can intersect" is the odd one out. Also note that A and D contradict each other, so one of them is usually the answer.
