Consider the given two statements:
| Statement I: | The outer nuclear membrane usually remains continuous with the endoplasmic reticulum and also bears ribosomes on it. |

| 1. | Statement I is correct; Statement II is correct |
| 2. | Statement I is correct; Statement II is incorrect |
| 3. | Statement I is incorrect; Statement II is correct |

Identify the incorrect statement:
| 1. | Centrosome is an organelle usually containing two cylindrical structures called centrioles. |
| 2. | Both the centrioles in a centrosome lie parallel to each other in which each has an organisation like the cartwheel. |
| 3. | Centrioles are made up of nine evenly spaced peripheral fibrils of tubulin protein where each of the peripheral fibril is a triplet. |
| 4. | The central part of the proximal region of the centriole is also proteinaceous and called the hub. |
