For a matrix [M] \(= \left[ {\begin{array}{*{20}{c}} {\frac{3}{5}}&{\frac{4}{5}}\\ x&{\frac{3}{5}} \end{array}} \right]\), the transpose of the matrix is equal to the inverse of the matrix [M]T = [M]-1. The value of x is given by

• A. \(- \frac{4}{5}\)
• B. \(- \frac{3}{5}\)
• C. \(\frac{3}{5}\)
• D. \(\frac{4}{5}\)
