The correct option is C Sampson Kempthorne
Sampson Kempthorne (1809–1873) was an English architect who specialised in the design of workhouses, before his emigration to New Zealand. Kempthorne came up with two designs – the square plan and the hexagonal or "Y" plan – both contained sections for the different types of inmates (men, women, boys, girls, infirm). The space between different wings was used to provide areas where inmates could exercise – segregated from the other groups. Kempthorne designed workhouses in Abingdon, Andover, Bath, Crediton, Hastings, and Newhaven. Hence, Option A is correct.
