If $A = \begin{bmatrix} 2 & 1 & 1 \end{bmatrix}$ denotes the row vector representing the number of tourists from Chennai (each element represent the number of tourists from Chennai to Manali, Sikkim and Meghalaya, respectively) in December 2019, and $C = \begin{bmatrix} x_1 & x_2 & x_3 \end{bmatrix}$ be the row vector representing the number of tourists from Chennai in December 2020 (where $x_1$, $x_2$ and $x_3$ denote the number of tourists from Chennai to Manali, Sikkim and Meghalaya, respectively) and we have the following equation $AB = C$, then which of the following matrices can represent $B$?
