Answer: E)
x^2+10x+25

Explanation:

Let the number x .

Given statement : A number is increased by 5, and then squared.

Number is increased by 5= x+5

Square of (x+5) is written as

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

[Using identity
(a+b)^2=a^2+2ab+b^2

Hence, the correct expression which represents the given statement is

x^2+10x+25
