(B) Given the equation is $ax + 3y = 21$.Since the graph passes through the point $(5, 2)$,the coordinates $x = 5$ and $y = 2$ must satisfy the equation.Substituting the values of $x$ and $y$ into the equation:$a(5) + 3(2) = 21$$5a + 6 = 21$$5a = 21 - 6$$5a = 15$$a = \frac{15}{5}$$a = 3$Therefore,the value of $a$ is $3$.
