(a) Energy stored per unit volume,

E = 1/2 * stress * strain

We know that,

E = 1/2 * stress * stress/Y = 1/2 .S2/Y

y= stress /strain
strain=stress/y
e= ½ *stress*strain
e= 1/2(stress*stress)/y
e=1/2 s^2/y
the answer is option (a)

Dear Student,
Please find below the solution to your problem.

y= stress /strain
strain=stress/y
e = ½ *stress*strain
e = 1/2(stress*stress)/y
e = 1/2 s^2/y
e = s^2/2y

Thanks and Regards
