Concept:

Bearing capacity factors:

\(N_q=N_ϕ\times e^{\pi .tanϕ}\)

Where \(N_ϕ =tan^2(45^\circ+{ϕ\over 2})\) = influence factor

\(N_\gamma=1.8tanϕ(N_q-1)\)

\(N_c=cotϕ(N_q-1)\)

Nc, Nq, and \(N_\gamma\) are dimensionless bearing capacity factors, depending only on the angle of shearing resistance (ϕ) of the soil. Hence option (2) is the correct answer.
