Answer 2

Solution :-

Given points are collinear

∴ area of triangle is zero

Area of triangle :-

$\tt \bf\left|\dfrac{x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1- y_2)}{2}\right|$

$: \implies \tt \left| \dfrac{1(0 - b) + 0(b - 2) + a(2 - 0)}{2} \right|= 0$

$: \implies \tt \dfrac{ - b + 2a}{2} = 0$

$: \implies \tt 2a - b = 0$

$: \implies \tt 2a = b$

Correct option :- A
