The answer is [D] b'coz pile foundation is used where the depth of foundation is greater than it's width so as to transfer axially and friction load throughout larger area below hard strata.

Answer should be all of the above because End bearing piles are transfer load at lower end in a hard stratum, Friction piles transfer load by skin friction.

Yes, All the given options are correct.

What about option D? Thanks in advance.

Actually answers is all the above. Any other piles are following the statement?

I think all options are correct.

I feel all the options are correct.

The all above statements are correct.

Question is incorrect as Pile transfer the load by End Bearing and Friction both,

In case of sand Load transfer is done by skin Friction generated due to friction between the pile surface and the soil particles around the surface of the pile.

In case of availability of Hard Strata at certain depth (mostly in case of BLack cotton Soil) Load transfer takes by point transfer of load at the end of the pile.

Also in many cases load transfer can be done by both Friction and End bearing for example in Coastal areas where sand is present over certain depth and then hard strata is available.

I think all the answers are correct. Because there are different types of piles like bearing and friction piles.
