Answer: Last option.

Explanation:

By definition, the square of a binomial is:


(a+b)^2=a^2+2ab+b^2\\\\(a-b)^2=a^2-2ab+b^2

Keeping the above on mind, you have the following expression given in the problem:


(x+5)^2

Therefore, if:


a=x\\b=5

You obtain the following trinomial:


(x+5)^2=x^2+2(x)(5)+5^2=x^2+10x+25

Therefore, the answer is the last option.
