Consider a bar of Diameter ‘D’ of length (L) embedded in a large concrete block. If a pull out force P being applied. Let σ_band σ_st be the bond strength (between the bar and concrete) and the tensile strength of the bar respectively. If the block is held in position and material of the block does not fall, which of the following options represents the maximum value of P?

Maximum of $(\;{π\;}/{4} × D^{2} × σ _{b})$ and (π × D × L× σ _st)
Maximum of $(\;{π\;}/{4} × D^{2} × σ _{st})$ and (π × D × L× σ_b)
