The correct answer is B. The portico of the Foundling Hospital was a public shelter.
The Foundling Hospital of London (England), was founded in 1739 by the ship captain and philanthropist Thomas Coram. It was established as a children's home for the "education and upkeep of people at risk and young children." At that time, the word "Hospital" was used in a broader sense as it is interpreted today, and simply indicated a "host institution" for the less fortunate.
