Given:
A = (blue, orange, red, yellow, green)
B = (silver, orange, blue, gold, yellow)
A ∩ B is the intersection of two sets A and B. The sets contain all elements of A that also belong to B.
In other words, the intersection results in a set of numbers that the two sets have in common.
The colors that A and B have in common are Blue, Orange, and Yellow.
Therefore, A ∩ B = {Blue, Orange, Yellow}
The answer is the 3rd option.
