this is the correct answer options are wrong

Answer 2

$\huge\pink{\boxed{\green {\mathbb{\overbrace {\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{ur\: answer }}}}}}}}}$

Let P(x)=x(square)

+3ax−2a

Given, (x−2) is a factor of P(x)

x−2=0

x=2

∴P(2)=0

⇒2 (square)

+3a(2)−2a=0

⇒4+4a=0

⇒a=−1

option (D) is your answer..
