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

All of these

For horizontal stiffeners, d is the clear distance between the horizontal stiffener and the tension flange

d is the distance between flange angles or the clear distance between flanges
