Write the correct alternative answer for each of the following questions.

Which of the following is a linear polynomial?

A polynomial is said to be linear if the highest power of the variable is one. So among the options x + 5 only has highest power as one.


Option (B) is not correct as the highest degree of the variable is 2 and the equation is quadratic.


Option (C) is not correct as the highest degree of the variable is 3 and the equation is cubic.
