Explanation / Answer

The regression equation will be of the form of:

Expenditure = a + b*Income + c*age + d*(Income*Age)

Given that main effect of age is not statistically significant i.e. c = 0

So for Income = 0,

Expenditure = a

So there is no interaction term and hence, any association between ae and expenditure if income is 0 is not statistically significant.

Option D is correct.
