Explanation:

Charges which are alike or similar are repulsive in nature or we can say that like charges repel each other.

Whereas opposite or unlike charges attract each other.

On the other hand, when a charged object is brought in contact with a neutral object then the neutral object acquires an opposite charge which reads to attraction between both the objects. This process of inducing the charge is known as induction.

Thus, we can conclude that the following statements are true.

  • Like charges repel.
  • Unlike charges attract.
  • Charged objects attract neutral objects due to induction.

astra-53 [7]

Answer: <u><em>Option B; It traps light energy and converts it into chemical energy.</em></u>

<h2>Explanation: This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.</h2><h2></h2><h2>This pigment is present only in plants, so option A is incorrect.</h2><h2></h2><h2>This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.</h2>
