Pick up the incorrect statement from the following:

• The retaining wall should be structurally capable to resist the applied earth pressure
• The section of the retaining wall should be so proportioned that it may not overturn by the lateral pressure
• The retaining wall should be safe against sliding
• The foundation of the retaining wall should not be stressed beyond safe bearing capacity ; due to its weight and the force resulting from the earth pressure
• to drain off water from the earth retained, weep holes are provided near the top of the retaining wall.
