Concept:In a magic square, the sum of every row, column, and diagonal is the same.Explanation:From the first row: 13+12+17=42.So every row, column, and diagonal must total 42.Use the second row: E+F+10=42.But we need the column containing F, which is the middle column: 12+F+16=42.Simplify: F+28=42.Thus: F=42−28=14.Answer:F=14, so the correct option is A.
