**Hint:**Best way to approach here is take an example or two and try calculating their cubes to see if the statement is true or false.

__Complete step-by-step answer__:According to the given information it is given that number that ends with 5 also the cube of that number ends with 25

Let’s discuss about the concept of square and cubic operation as we know that according to the square operation gives the output of the multiple of input by itself i.e. square of a is given by $a \times a$whereas in the cubic operation gives the output of the multiple of the input by itself three times i.e. cube of b is given by $b \times b \times b$

Since it is given that square of a number ends with 5 also the cube of the same number ends with 25

So, let’s suppose the number is 5

As we know that square of number 5 is given by $5 \times 5 = 25$

So, let’s check the cube of 5 which is given by $5 \times 5 \times 5 = 125$

Here the number 5 satisfies the statement

To check that whether the statement applies for every number

Let’s 15 be the number

As we know that square of number 15 is given by $15 \times 15 = 225$

So, let’s check the cube of 15 which is given by $15 \times 15 \times 15 = 3375$

Since the square of 15 ends with 25 whereas the cube of 15 ends with 75

So, here the number 15 doesn’t satisfy the statement

Therefore, the given statement if false

**Hence, option B is the correct option.**

**Note**:In the above solution we used the term “operation” which can be explained as a method which includes an operand and an operator such as addition operation, subtraction option and division operation as in the above solution we used the square and cubic operation. The square and cubic operations are unary operations which require only one operand whereas the operations which require more than one operand are called binary operations.
