option d
explanation:
since the case is that of a simply supported slab so using the RANKINE GRASHOFF theory we have maximum short span moment =(r^4/(1+r^4)x( wl^2/8) .here the term wl^2/8 is actually the maximum moment since both the spans are same. so the coefficient of this maximum moment =r^4/(1+r^4), putting the value of r=1(coz both the spans are same) we get:
1^4/(1+1^4) = 1/2=0.5. hence the answer is 0.5 which is multiplied to the maximum bending moment.
