Read the following statements and identify the correct answer.
Statement A: For simply supported deep beams when \({l\over D}<1\) then the lever arm is equal to 0.6\(l\). Where \(l\) is effective span and D is overall depth.
Statement B: The pitch of helical reinforcement in the circular column should not be less than 4dc and 25 mm (whichever is maximum). Where dc is the diameter of the core.
Statement C: If the permissible stress in concrete is 6.66 MPa then the modular ratio is 14.
Statement D: A beam shall be deemed to be a deep beam where the ratio of effective span to overall depth, \(l\over D\) is greater than 2.5 for a continuous beam.
