Pick up the correct statement from the following:
The effective span of a simply supported beam is clear span plus its effective depth or centre to centre of supports whichever is less
The effective span of a simply supported slab is clear span plus its effective depth or centre to centre of supports whichever is less
The effective span of a continuous beam or slab is the clear span plus its effective depth or centre to centre of supports whichever is less, provided the width of the support is less than of clear span
For spans with roller or rocker bearing, the effective span is the distance between the centres of bearings
All the above.

Pick up the correct statement for the web stiffeners.
vertical stiffeners are spaced at a distance not greater than 1.5 d and not less than 0.33 d
d is the distance between flange angles or the clear distance between flanges
for horizontal stiffeners, d is the clear distance between the horizontal stiffener and the tension flange
all the above.
