A. HSLa Color

B. HSL Color

C. RGBa Color

D. RGB Color

Answer: Option A

Solution(By Examveda Team)

An HSLa is specified via a function style hsla(hue,saturation, lightness, alpha), where hue, saturation, and lightness are the same as standard hsl() values, and the alpha channel value for defining opacity is a number between 0 (fully transparent) and 1 (fully opaque).
