Answer:

option A.

Step-by-step explanation:

1 -  \frac{1}{3} x \geqslant  \frac{1}{2}  (x - \frac{3}{5} ) \\  \frac{3 - x}{3}  \geqslant  \frac{1}{2}(  \frac{5x - 3}{5} ) \\  \frac{3 - x}{3}  \geqslant  (  \frac{5x - 3}{10 } ) \\ \frac{3 - x}{3}  \times 3 \geqslant  (  \frac{5x - 3}{10 } ) \times 3 \\ 3 - x \geqslant ( \frac{5x - 3}{10} )3 \\ (3 - x) \times 10 \geqslant( \frac{5x - 3}{10} )3 \times 10 \\  (3 - x) \times 10 \geqslant(5x - 3)3  \\ 30 - 10x \geqslant 15x - 9 \\ 30 + 9 \geqslant 15x + 10x \\ 39 \geqslant25x \\   \frac{39}{25}  \geqslant x

therefore, the answer's A.
