In PROC GLMSELECT with SELECTION=LASSO, the PATH= option is specified. What does the solution path represent?

Short Explanation and Infographic
Here's the deal — c is correct because the LASSO solution path (also called the regularization path) shows how each coefficient changes as lambda varies. At maximum lambda, all coefficients are 0; as lambda decreases, variables enter the model one by one.

Full Explanation
C is correct because the LASSO solution path (also called the regularization path) shows how each coefficient changes as lambda varies. At maximum lambda, all coefficients are 0; as lambda decreases, variables enter the model one by one. The PATH= option saves these coefficient estimates at each lambda value to a dataset. A is wrong; stepwise visits specific model configurations, not a continuous regularization path. B is wrong; PATH= specifies an output dataset name. D is wrong; cross-validation fold sequences are not what PATH= represents.
