Pick up the correct statement from the following:

• When water table is above the base of a footing, the dry weight m should be used for soil below water table
• When water table is located somewhat below the base of a footing, the elastic wedge is partly of moist soil and partly of submerged soil, and a suitable reduction factor is used
• When water table is just at the base of the footing, no reduction factor is used
• None of these.
