The two true statements for the expansion are A and C.

Which statements are true?

In the expansion of (x + y)ⁿ, each one of the terms will have a total exponent equal to n, this means that we will have terms like:

[tex]x^k*y^j[/tex]

Such that k + j = n.

Particularly, we get the terms xⁿ and yⁿ only once, so the first statement is correct, the coefficients of these terms will be 1.

It is also true that the coefficients of:

[tex]x^k*y^j = x^k*y^k[/tex]

Are equal.

Then the two true statements are A and C.
