Explanation
The requirement explicitly states that the operation must not affect the dimensionality of the feature set. Dimensionality refers to the number of features (columns). Removing an entire column reduces the number of features, directly changing the dimensionality. This violates the stated constraint. Even if the column had only a few missing values, deleting it removes all valid data in that column as well, resulting in information loss and a smaller feature space.
