Observing the Pattern:
The sequence of figures follows a logical pattern in which the shaded area gradually increases. Each successive figure in the sequence shows a larger portion of the shape being shaded, following a systematic progression.
Identifying the Correct Option:
- By analyzing figures I to III, we observe that the shaded portion expands in a consistent manner.
- The next figure in the sequence should maintain this trend by increasing the shaded area further.
- Among the given options, option (b) correctly follows the pattern, making it the right choice.
Conclusion:
Since option (b) maintains the logical increase in shading seen in previous figures, it is the correct answer. The pattern remains consistent, ensuring the sequence is followed correctly.
