358. In case of triple-tandem compound arrangement in steam turbines
A.The steam from one casing flows to other, the shafts of both being coupled in straight line
B.The steam in any casing enters in the middle and flows in both the directions
C.The steam from one casing flows to other, the shafts. of both being in different planes
D.The steam flows from high pressure casing to intermediate pressure casing and then to low pressure casing, the shafts of all the three being coupled in one straight line
