This is just an educated guess. As the purple pigment, caused by anthocyanins, are on the bottom side of the plant, their purpose could probably be to direct the light.
Specifically, a purple pigment on the bottom of the plant would absorb certain wavelengths near the purple spectrum, and reflect other wavelengths back toward the portion of the plant with chlorophyll. In this way, light does not simply pass through the leaf, instead it is reflected back in towards the chlorophyll to maximize the amount of light being used for photosynthesis.
Answer: The charges of the objects are A: Positive and B: Negative.
Explanation-
The electric field lines are pictorial representation of the electric field in terms of imaginary lines.
The direction of electric field is away from the positive charge and is directed towards the negative charge.
In this question, the electric field lines are emerging from A and coming towards B.
Thus, the right answer is A: Positive and B: Negative.
