Answer:
A. Thinking that relationship-building is a waste of time
Step-by-step explanation:
Cross cultural study is done in order to understand the similarities and differences in between two or more cultures. Accordingly the studies require to know the different culture.
The culture you want to compare or identify similarity with, because only after knowing the culture one can identify them.
Accordingly, if one thinks that building relationships with other culture is not important and a mere wastage of time, it means it is an ignorance to the study of cross-culture.
