**Answer:**

B. Writing an equation is the most useful

**Step-by-step explanation:**

We are required to find the best method which can be used to find the value of a variable.

Since, we know,

*While writing an equation, we assign the dependent variable in terms of the independent variable.*

These equations can be easily solved using the methods such as substitution and elimination.

Thus, they give the exact value of the variables.

While options A, C and D, does not give the value of the variables over the domain.

**So, the best option useful to find the value of the variable is to write an equation.**

**That is, option B is the most useful.**
