Circumferential strain= pd/2tE(1-1/2m).
Longitudinal strain= pd/2tE(1/2-1/m).
Simply required= Longitudinal strain/ Circumferential strain.
= {pd/2tE(1/2-1/m)}/{pd/2tE(1-1/2m)}.
= {m-2/2m}/ { 2m-1/2m}.
= m-2/2m-1.
Option A is correct.

Sigma hoop=Pd/2t,
Sigma longi=Pd/4t,
Sigma long/Sigma hoop=1/2.

Now,
Strain longi = ( Sigma longi + M * Sigma hoop)/E.
Strain hoop=(Sigma hoop+M*Sigma longitudinal)/E.
Take ratio.
