I think A is correct but I am not sure. I really need to get this right thank you so much if you can help.

If it's SAS, then you should be able to name the sides, angles, and sides that match. What are they? That should convince you that you are right.

What makes you doubt your answer?

 

[JonahKane]

Well I see a side and I see an angle (The right angle). and I sees there’s another side that connects the two triangles so I’m going to put the answer is a

 

[Dr.Peterson]

Yes. What you have is AB = CB, ABD = CBD, and BD = BD. These are two sides and the angle between them, so they satisfy the conditions for SAS.
