        Option: D

D.  {(1, 1), (1, 2), (1, 3), (1, 4), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3, 3), (3, 4)}

Step-by-step explanation:

Sample space--

It is the set of all the outcomes of an event.

Let the sample space be denoted by the elements of the type (b,g) where b represent the outcome of the first draw i.e. picking a blue card and g denote the outcome of the second draw i.e. picking a green card.

Now, it is given that:

A box contains 3 blue cards numbered 1 through 3, and 4 green cards numbered 1 through 4.

Hence, the sample space is given by:

{(1,1), (1,2) , (1,3) , (1,4) , (2,1), (2,2) , (2,3) , (2,4) , (3,1), (3,2) , (3,3) , (3,4) }
