➺ It's likely to be <u>option D.</u>

➺ The first figure has a line which divides the circle ⭕ into 2 parts. The 2nd figure divides the circle ⭕ into 3 parts while the 3th figure divides the circle ⭕ into 4 parts. Obviously, the 4th figure then should divide the circle ⭕ into 5 parts. Checking all the given options,
- Option A. doesn't divide the circle ⭕ into any parts.
- Option B. divides the circle ⭕ into 3 parts
- Option C. divides the circle ⭕ into 4 parts.
- <u>Option D. divides the circle ⭕ into 5 parts.</u>
⟹ So, <u>option D.</u> is the correct answer.
