a.

Explanation of Solution

Relationship between X and Y being linear

Without knowing more details about the training data, it is difficult to know which training RSS is lower between linear or cubic...

b.

Explanation of Solution

Relationship between X and Y being linear

In this case the test RSS depends upon the test data, so we have not enough information to conclude...

c.

Explanation of Solution

Relationship between X and Y being non-linear

Polynomial regression has lower train RSS than the linear fit because of higher flexibility...

d.

Explanation of Solution

Relationship between X and Y being non-linear

There is not enough information to tell which test RSS would be lower for either regression given the problem statement is defined as not knowing “how far it is from linear”...
