Bottom Radiator Hose

[CJ101KT]

Have had my Elan S2 serviced today by Stratstone Lotus in Cardiff and they have pointed out a few things that could do with being changed and one is that the bottom radiator hose is swollen. I have looked on SJ's and Paul Matty's to find the correct part but this has given me a few options and slightly confusing for me as im not mechanical minded ... just technical lol.

SJ Sportscars lists:

Cooling system | Hoses
BOTTOM RADIATOR HOSE, (Inc. hose to recirculation pump) C100K0104F EACH 38.00

Cooling system | Hoses
BOTTOM RADIATOR HOSE, (With separate hose to recirc pump) A100K0113K EACH 27.40

Cooling system | Hoses
HOSE, HEADER TANK to PUMP to BOTTOM HOSE A100K0114K EACH 40.00

Are these the only possible bottom radiator hoses that would be described after my service as being corroded?
I don't want to be ordering the wrong parts

The S2 has a one piece which goes from the rad then splits to the pump and the header tank the SE has a metal tube conector and the pipe is in two pieces

So this one:

Cooling system | Hoses
BOTTOM RADIATOR HOSE, (Inc. hose to recirculation pump) C100K0104F EACH 38.00

Thanks for the help ...
