As it is mentioned that value of correlation (r) is -0.5 and variability in the variables are explained by the coefficient of determination and coefficient of determination is equal to r² hence the value of determination will be (0.5)²= .25 and such variations are explained in percentage term hence it will be 25% and by squaring negative sign will become positive hence the answer will be option (A). I hope it is understandable to you.
