Because it has only axial load and there is 3 axial load to be applicable in a space of 5m from A point so total is 10 each tonnes for 3 (10*3= 30 tonnes).

Ans:- A.
Sum of moment @ rigid joint (below A) = zero.
10*15 = Hb*5.
Hb = 30 tonnes.
Sum of moment @ rigid joint (below A) = zero.
10*15 = Hb*5.
Hb = 30 tonnes.

What is Hb?
Suresh said:

Hb is horizontal reaction at B.

Calculate all horizontal component of truss and find the answer.

Take sum of moments at other rigid joint = 0.
10 * 15 = h * 5.
Then, H = 30.
10 * 15 = h * 5.
Then, H = 30.

Considering Zero moment at point A, B is point below point A.
Rbx=horizontal reaction at B, Rax=horizontal reaction at A
Ma=moment at A.
E Ma=0
(-Rbx5)+(15x10)=0
-5Rbx= -10x15=150
Rbx=30 ton.
E R=0 ->+.
-Rax+Rbx=0.
Rax=Rbx=30 ton.
Rbx=horizontal reaction at B, Rax=horizontal reaction at A
Ma=moment at A.
E Ma=0
(-Rbx5)+(15x10)=0
-5Rbx= -10x15=150
Rbx=30 ton.
E R=0 ->+.
-Rax+Rbx=0.
Rax=Rbx=30 ton.

10x15 = Hx5.
H = 30 tonnes.
H = 30 tonnes.
