What is the maximum allowable separation between exterior wall axes for a roof truss system without intermediate supports and with 60 cm eaves?

The maximum allowable separation between exterior wall axes is given in the table.
The validity of the results is limited to a maximum separation between exterior wall axes of 12 m.
For eaves greater than 60 cm, the maximum tabulated distance must be reduced by twice the difference between the actual eaves and 60 cm.
For eaves less than 60 cm, the distance can be increased by twice the difference between 60 cm and the actual eaves length.
a) Only statements I and II are correct.
b) Only statements II and III are correct.
c) Only statements III and IV are correct.
d) All statements are correct.
