It is easier to perform two tasks at the same time if:

a. The visuospatial sketchpad and the phonological loop each angle one taskb. Both tasks are handled by the visuospatial sketchpadc. Both tasks are handled by the phonological loop d. The central executive is deactivated during the dual task situation

Option a. The visuospatial sketchpad and the phonological loop each angle one task

Explanation:

The task is easier to handle if the work is held together in the two work areas. This enables a person to work much faster and also more efficiently. The visuospatial sketchpad and the phonological loop each angle one task. Placing these at such an orientation allows the work to be done much faster.
