which hybrid orbitals would be formed if one s orbital and three p orbitals combined?\no sp\no sp²\no sp³\no…

Brief Explanations:

Hybrid orbitals are named based on the number and types of atomic orbitals that combine. When one s - orbital and three p - orbitals combine, the resulting hybrid orbitals are called $sp^{3}$ orbitals. The naming convention for hybrid orbitals is that the superscripts on the letters represent the number of each type of atomic orbital involved in the hybridization process. Here, 1 s - orbital and 3 p - orbitals are combined.

Answer:

C. $sp^{3}$
