# If $A$ and $B$ are square matrices of equal degree,then which one is correct among the following

(A) A+B=B+A

(B) A+B=A-B

(C) A-B=B-A

(D) AB=BA

If $A$ & $B\rightarrow$ Square matrices of same degree then matrices A and B can be added or subtracted or multiplied.
By algebra of matrices the only option is $A+B=B+A$
Hence (a) is the correct answer.
