I want to store a different colour for each individual Die object, so that I can display that Die later with that colour. What must I add to my class?

Question $2$ Select one:

a$.$

A comment above the class indicating what colour it should be$.$

b$.$

A new object called colour, instantiated as colour $=$ Die$(\text{'}$blue$\text{'})$

c$.$

An additional $\_\_$init$\_\_()$ method that takes colour as its only argument.

d$.$

An additional attribute called colour to the existing $\_\_$init$\_\_()$ method.
