What is the value of the potential energy of the system at Position 2 with the datum at the level of pin B?

Which of the following best approximates the total mechanical energy at Position 3?

 

Two identical slender rods AB and BC (MAB = mBC = 1.5 kg) are welded together to form an L shaped assembly. The assembly is pressed against a spring at D and
released from the position shown (Position 1). The assembly then passes through the position where rod AB forms an angle of 30° counterclockwise from the
horizontal (Position 2). Knowing that the maximum angle of rotation of the assembly in its current motion is 90° counterclockwise (Position 3), answer the
following.
