Three identical thin rods, each of mass \[m\] and length \[\ell \], are joined to form an equilateral triangular frame. The moment of inertia of the frame about an axis parallel to its one side and passing through the opposite vertex is

• A. \[\frac{5}{2}m{{\ell }^{2}}\]
• B. \[\frac{5}{4}m{{\ell }^{2}}\]
• C. \[\frac{3}{2}m{{\ell }^{2}}\]
• D. \[\frac{5}{3}m{{\ell }^{2}}\]
