(B) Given that $a, b, c$ are in Arithmetic Progression ($A$.$P$.).By the property of $A$.$P$.,we have $2b = a + c$,which can be rewritten as $a - 2b + c = 0$.The equation of the straight line is $ax + by + c = 0$.Comparing this with the condition $a(1) + b(-2) + c = 0$,we can see that the line satisfies the equation for the point $(x, y) = (1, -2)$.Therefore,the straight line $ax + by + c = 0$ will always pass through the point $(1, -2)$.

If $a, b, c$ are in $A$.$P$.,then the straight line $ax + by + c = 0$ will always pass through the point
