Given below are two statements:
| Statement I: | Aldehydes and ketones having at least one \(\alpha\)-hydrogen undergo aldol condensation in the presence of dilute alkali as catalyst. |
| Statement II: | When aldol condensation is carried out between two different aldehydes, it is called cross aldol condensation. Ketones do not give this reaction. |
In light of the above statements, choose the most appropriate answer from the options given below:
| 1. | Statement I is correct and Statement II is incorrect. |
| 2. | Statement I is incorrect and Statement II is correct. |
