Homogeneity of regression requires that:

a the interceptof the regression between the DV and CV(s) be constant across groups.

b. There be an interaction between the IV(s) and the CV(s).

c. the slope of the regression between the DV and the CV(s) be constant across groups.

d. all of the above

Solution

Homogeneity of regression requires the slopes of the relationship between the CV and the DV are different for your intervention and control group.
