If ⊗ is an operation such that a ⊗ b = 2a when a > b, a + b when a < b, a2 when a = b, then $$\left[ {\frac{{\left( {5 \otimes 7} \right) + \left( {4 \otimes 4} \right)}}{{3\left( {5 \otimes 5} \right) - \left( {15 \otimes 11} \right) - 3}}} \right]$$is equal to?

• A. $\frac{1}{3}$$
• B. $\frac{{14}}{{23}}$$
• C. $\frac{2}{3}$$
• D. $\frac{{14}}{{13}}$$
