(D) Statement $1$ is false because $T$. $W$. Engelmann's experiment demonstrated that photosynthesis occurs primarily in the blue and red regions of the light spectrum,not green and orange. Furthermore,the photolysis of water is a complex process not explicitly described by his action spectrum experiment.Statement $2$ is true. Engelmann used aerobic bacteria as a tool to detect the sites of $O_2$ evolution. He observed that these bacteria accumulated mainly in the regions of blue and red light,indicating that these are the areas where maximum photosynthesis (and thus $O_2$ release) occurs.
