How do you change an object's opacity?

• A. Select the object, open the Properties panel and change the opacity.
• B. Right-click and choose Opacity
• C. Use the Brush tool with opacity
• D. Edit > Transparency > Opacity

Answer: (A)

Changing an object's opacity means adjusting how transparent it appears, and the quickest way to do this in Illustrator is to select the object and use the Opacity control in the Properties panel. The Opacity setting applies to the entire object, so the fill, stroke, and any effects all become more or less transparent together as you adjust the value. This panel is context-sensitive, so it shows the relevant controls as soon as you have something selected, making the change fast and intuitive. The other options don’t fit because there isn’t a right-click Opacity option, the Brush tool changes painting opacity for drawing rather than the overall object's transparency, and Edit > Transparency > Opacity isn’t a standard menu path in Illustrator. You could also reach the same setting through the Transparency panel (Window > Transparency), but using the Properties panel is the most direct method.
