Answer 2

The correct answer is option (B.) RGBa.

Explanation:

• RGBa is a CSS3 Color Feature like RGB color but adds an alpha channel value to specify the opacity of the color.
• An RGBa is specified via a function style rgba(r,g,b,a) value, where colors r, g, and b are specified as a decimal value from 0 to 255 or a percentage from 0 to 100%.
• The alpha channel value for defining opacity is a number between 0 which is fully transparent and 1  which is fully opaque.
• Values which is outside this range will be rounded up or down to fit the closest value.
