The correct answer is C. Can be gender-inclusive
Step-by-step explanation:
Language is gender-inclusive if words do not exclude a particular sex or gender. For example, the word "mankind" used to refer to human species is considered as non-inclusive because it can be interpreted as an exclusion of women. In this context, if the manager changes "chairman" by "chair" the manager is showing language can be gender-inclusive because the manager changed the term to make it general and avoid the exclusion of women.
