B is correct.
(B -3d)+S * 2 ÷ 4g +S *2 ÷4g.
300-3 * 75) + 50*2÷4 * 100 +(50 * 2÷4 * 100),
= 237.5.
(B -3d)+S * 2 ÷ 4g +S *2 ÷4g.
300-3 * 75) + 50*2÷4 * 100 +(50 * 2÷4 * 100),
= 237.5.

300-3 * 25 + {(50^2)/4*100}*2 = 237.5 mm.

B - nD + n'P^2/4G.
Here;
P = pitch.
G = gauge distance.
Here;
P = pitch.
G = gauge distance.

Suppose upper rivet 1 , middle 3, and bottom 2.
The section can fail along either 1--2 or 1--3--2 we give a minimum net area for the strength of the member.
Let, sectn 1-2, the net area = (b-nd+n's²/4g)t.
For width, t=1 let, (300-2×25) for pitch zero:
Width 250mm
Now, for sect 1-3-2.
Net Width= (300-3×25+2×50²/4×100) = 237.5
I.e minimum among 237.5mm✓

Answer is b.
300 - 3 * 26.5 + (2 * 50^2/4 * 100) = 233 mm.
300 - 3 * 26.5 + (2 * 50^2/4 * 100) = 233 mm.
