Which of the following group is present in animal cells?

Animal cells are eukaryotic cells characterized by the presence of a membrane-bound nucleus, cytoplasm, and various organelles like mitochondria [2]. The cell membrane (plasma membrane) encloses the cytoplasm and nucleus, regulating the entry and exit of materials [1]. Unlike plant cells, animal cells lack a cell wall and chloroplasts, which are specific to plants for structural support and photosynthesis [3]. While plant cells typically contain a large central vacuole for turgor pressure, animal cells either lack vacuoles or possess very small, temporary ones [3]. Therefore, the group containing the nucleus, cell membrane, mitochondria, and cytoplasm correctly identifies components universally present in animal cells [4]. Option 1 is incorrect due to the 'cell wall', and Option 2 is incorrect due to 'chloroplasts', both of which are plant-specific structures [3].
