Aflashing yellow light at an intersection means

a. stop and yield to vehicles that arrived first and vehicles to your right
b. slow down and yield to cross traffic before proceeding with caution
c. stop before entering the intersection unless you cannot do so safely
d. stop only if there is already a vehicle stopped at the intersection

These are two different questions.

The anwer for first question: A flashing yellow light at an intersection means .  Is: B. slow down and yield to cross traffic before proceeding with caution

And the answer for the second quesiton: regarding the red triangle yield sign is: A. Slow down and be ready to stop if needed to let cross traffic pass before you proceed.

Explanation:

Ok, so first of all the first question means that if you are in a road that leads to an intersection you have to slow down and find a secure position to go into the intersection. However, you might have to stop if there is any sign of risk or danger of collision. Those yellow flash signs are to prevent cross collisions.

The second sign means that you have to stop before advancing because you don't have the right to past first or before the cars in your intersection cross.
