Answer the following question given this paragraph: 

The methane and ammonia examples illustrate the connection between orbital hybridization and the VSEPR model. The electron domain geometry predicted by VSEPR leads directly to the type of hybrid orbitals that must be formed to accommodate that geometry. Both methane and ammonia have tetrahedral electron domain geometries and thus both undergo sp 3 hybridization.


Q: What type of hybridization does ammonia undergo?

 Choices:

- h2O hybridization

- ionic hybridization

- nh3 hybridization

- sp 3 hybridization

A:
sp 3 hybridization
