Solution

The correct option is C Both 1 and 2
Static Cone Penetration Test - Also known as Dutch Cone for CPT, it gives a continuous record of variation of both cone resistance and friction resistance with depth. CPT however does not yield any sample. It is suitable for soft clay and silts and fine to medium sand deposits.
