Based on the context provided, it appears you're referring to relationships regarding lines and angles in a construction diagram. However, without the actual diagram and the context of what m || f represents, I cannot definitively select the correct statement.
If "m || f" indicates that lines m and f are parallel, then the other statements seem to reference segments (AQ, BD, AC, etc.) within the diagram, but without knowing their relationships or positions relative to each other or the lines mentioned, it's impossible to determine the correct statement.
Please provide additional context or details about the diagram or the relationships between the elements mentioned.
