The representative liquid limit and plastic limit values of a saturated consolidated clay deposit are 60% and 30%, respectively. The saturated unit weight of the soil is 19 kN/m3. The water table is at 8 m below ground level. At a depth of 10 m from the ground surface, the undrained shear strength of the soil will be nearly

• A. 37.7 kN/m2
• B. 33.5 kN/m2
• C. 29.3 kN/m2
• D. 25.1 kN/m2
