Final answer:
The term 'multifocus theatre' is not typically used to describe a standard theatrical venue, whereas proscenium stages, thrust stages, and created or found spaces are common performance spaces.
Correct option is B.
Step-by-step explanation:
Among the options provided, the term 'multifocus theatre' is not commonly recognized as a standard type of performance space and is not typically used to describe a theatrical venue, making it the answer that is not ordinarily used for performances. On the other hand, a proscenium stage is very common and is designed with the audience facing the stage, often used for larger and more technically demanding productions. A thrust stage allows for more intimacy and a three-sided audience arrangement, showing technical aspects of a production, while a created or found space refers to non-traditional venues like streets or urban environments that are used for performances, often seen in street theatre.
Correct option is B.
