Answer:
a. eliminating variables for a multiple regression model
Step-by-step explanation:
Variance inflation factor (VIF) could be described as a measure to the amount of multi-collinearity in a set of multiple regression variables. In mathematics, the variance inflation factor for a regression model variable will be equal to the ratio of the overall model variance to the variance of a model that includes only that single independent variable. Accordingly, this ratio is evaluated for every independent variable and the high factor shows the associated independent variable which is highly collinear to the other variables which can be included in the model.
A multiple regression can be utilized in the case of when there is a need to test the effect of multiple variables on a particular result. As a result, the dependent variable is the outcome which is being acted upon by the independent variables, that are the inputs into the model. Multi-collinearity appears in the case of when either there is a linear relationship, or correlation, between one or more of the independent variables or inputs and it makes the establishment of a problem in the multiple regression due to since the inputs are all influencing each other, they are not actually independent.
Answer:
The third option is the correct one.

For similar triangles, the angles are the same, but the distances between corresponding vertices is only proportional
