Answer:  Option 'B' is correct.

Step-by-step explanation:

Since we have given from the figure shown

AB = 2

BC = 5

AC = √29

We need to find ∠C in ΔABC:

For this we will use "Trigonometric Ratios" :

[tex]\tan C=\frac{AB}{BC}\\\\\tan C=\frac{2}{5}\\\\\tan C=0.4\\\\C=\tan^{-1}(0.4)\\\\C=21.8\textdegree\\\\C=22\textdegree\ approx.[/tex]

Hence, Option 'B' is correct.
