Answer:
The correct answer is 3. It could be a plant cell.
Step-by-step explanation:
A plant cell is a eukaryotic cell which contains a well-defined membrane-bound nucleus and other membrane-bound organelles. The main difference in plant and animal cells is that animal cells do not have cell walls and chloroplast which is found in the plant cells.
So when a cell wall and chloroplast are seen under the microscope then it can be concluded that the cell is a plant cell. In plant cell, chloroplast is that organelle that is responsible for trapping sunlight and do photosynthesis which is required to form glucose. Therefore the correct answer is 3.
