Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

Between-subjects (or between-groups) study design:

Different people test each condition, so that each person is only exposed to a single user interface

So,

a is not TRUE

b. same participants is not observed in each group. So, b is not TRUE

c. n*k participants are required , if we have n participants accross k variants. C is TRUE

d. this is false. between-subjects ANOVA design can happen between-groups.

Answer is C.
