To apply an effect to a selected layer in Adobe After Effects, there are multiple methods available, making option C the correct answer.
When you choose a method, dragging the desired effect from the Effects & Presets panel directly onto the layer in either the Timeline or Composition panel is a quick and intuitive way to apply effects. This method allows for immediate visual feedback, enabling users to see the impact of the effect on the layer in real-time.
Alternatively, using the Effect menu is another standardized way to apply effects. By selecting a layer and navigating to the Effect menu at the top of the application, users can access a comprehensive list of effects categorized neatly. This method is particularly useful when dealing with numerous effects or when one prefers to search through effects rather than dragging them directly.
Both methods are valid and provide flexibility depending on the user’s preference and workflow. Therefore, recognizing that either option applied to a selected layer effectively supports the conclusion that both methods work, reinforcing option C as the comprehensive response.
