B Correct answer
Explanation

In a bag, there are total 12 (5 + 4 + 3) balls. For getting 3 red balls, the probability is 3/12 and for getting 4 green balls, the probability is 4/12. Hence, getting either a red ball or a green ball by addition principle, the probability will be (3/12) + (4/12) = 7/12. Hence, it is the correct answer.
