To find the probability that a randomly selected marble is blue, we need to determine the total number of marbles in the bag and the number of blue marbles.

In this case, the bag contains 4 red marbles, 3 blue marbles, and 7 green marbles, making a total of 4 + 3 + 7 = 14 marbles.

Since there are 3 blue marbles, the probability of selecting a blue marble is 3/14.

Therefore, the correct answer is option D, 3/14.
