All of the listed options are methods by which a gene can be isolated from a DNA library. 
- In situ colony hybridization and in situ plaque hybridization involve identifying a colony or plaque containing the desired gene through hybridization with a specific probe. 
- Genetic complementation involves introducing the library into a mutant cell or organism in which the gene of interest is non-functional, and identifying the library clone that restores function. 
- Genetic selection involves selecting for library clones that exhibit a specific phenotype of interest.
