Sure, let's break down the steps to solve the question:

We need to find the value of the expression [tex]\(2.1 + 3.32 - 1.4\)[/tex].

1. Start with the two numbers being added together: [tex]\(2.1 + 3.32\)[/tex].
- First, align the decimal points for clarity:
[tex]\[ \begin{array}{r} 2.1 \\ +3.32 \\ \hline 5.42 \\ \end{array} \][/tex]

2. Now, subtract [tex]\(1.4\)[/tex] from the result:
- Again, align the decimal points:
[tex]\[ \begin{array}{r} 5.42 \\ -1.4 \\ \hline 4.02 \\ \end{array} \][/tex]

So, the value of [tex]\(2.1 + 3.32 - 1.4\)[/tex] is [tex]\(4.02\)[/tex].

Therefore, the best answer is:
B. 4.02
