Which p-orbitals overlapping would give the strongest bond?

What type of overlapping take place in a sigma and a pi bond?

A covalent bond will be formed by the overlapping of atomic orbitals having single electron of opposite spin, according to the overlapping of atomic orbitals the covalent bond may be of two types : (i) Sigma bond (sigma) " " (ii) Pi bond (pi) Sigma bond is stronger bond than the Pi-bond. If atomic orbitals overlap about the nuclear axis then sigma bond is formed but when atomic orbitals overlap sideway then Pi-bond is formed. Compound having maximum bond angle is :

If atomic orbitals overlap about the nuclear axis then sigma bond is formed but when atomic orbitals overlap sideway then Pi-bond is formed. The strength of bonds formed by 2s-2s,2p-2p and 2p-2s overlap has the order :
