The first part has to be either Heads or Tails The second part can be any number on a normal dice which is 1 through 6. A is wrong because it has nothing about the dice. B is wrong because it has nothing about the coin toss. C is wrong because 8 is not a number on a normal dice.
Therefore, D is your answer since it has a result from a coin toss and then a result from rolling a dice.
