Correct Answer

✅ Option d — J-shaped curve

All Options:

  • ABell shaped curve
  • BMixed curve
  • CU-shaped curve
  • DJ-shaped curve

Detailed Solution & Explanation

Let us analyze the shapes of frequency curves based on their definitions:
1. **J-shaped curve**: Starts with a minimum frequency at one end and increases gradually to reach its maximum frequency at the other extremity. (e.g., mortality rates at advanced ages, or wealth distribution). It can be regular or inverted.
2. **U-shaped curve**: Has maximum frequencies at both extremities and a minimum frequency in the middle.
3. **Bell-shaped curve**: Starts low, rises gradually to a single peak (maximum frequency) in the middle, and then falls symmetrically (e.g., normal distribution).

Therefore, a curve that starts with minimum frequency and ends with maximum frequency is a J-shaped curve.

Hence, **Option D** is the correct answer.
