Option A:
is true about the triangle.
Explanation:
The measurements of the right triangle ABC is
,
and 
The image of the triangle having these measurements is attached below:
Option A: 
Using Pythagorean theorem, we have,



Thus, the length of AC is 
Therefore, Option A is true about the triangle.
Hence, Option A is the correct answer.
Option B: 
Using Pythagorean theorem, we have,




Thus, the length of BC is 
Therefore, Option B is not true about the triangle.
Hence, Option B is not the correct answer.
Option C: 
Using Pythagorean theorem, we have,




Thus, the length of BC is 
Therefore, Option C is not true about the triangle.
Hence, Option C is not the correct answer.
Option D: 
Using Pythagorean theorem, we have,



Thus, the length of AC is 
Therefore, Option D is not true about the triangle.
Hence, Option D is not the correct answer.
