Pick out the wrong statement pertaining to 'Horton sphere' used for the storage of liquid ammonia.

Horton sphere is used for the storage of liquid at sub-zero temperature at very high pressure upto 200 kg/cm²

Diameter of Horton sphere is normally 6 to 25 metres and it is supported by 6 to 12 nos. tubular or rolled section column

Horton sphere is used for the storage of gases and volatile liquid at a moderate pressure of 1 to 10 kg/cm²

Thickness of spherical shell is half that of the cylinderical vessel under same operating pressure condition. Besides, the ratio of surface area to volume is less for sphere than any other shape ; hen
