James's family business, J&J Interiors, sells and installs tile in bathrooms and kitchens. More and more of J&J's customers are asking for heater coils under bathroom floors, and James thinks there is a greater opportunity in heated tiles. In his effort to avoid domestic competition, he sets his sights on the vast Hasalot market. Much to his surprise, most of Hasalot's citizens do not yet have indoor plumbing and are accustomed to government-run communal baths. James realizes that his global marketing effort is hampered by

physical and environmental constraints

Explanation:

In this scenario James wants to introduce heater could under bathroom floors to the Hasalot market.

However most of the citizens do not have indoor plumbing and are accustomed to communal baths provided by the government.
