Explanation:
<span>The answer is b. have a change in dipole moment
When a molecule absorbs an infrared ray, its energy will increase. The energy will increase the rotational movement or the molecule. If the energy increases further, it will become the vibrational movement. Dipole moment will be increased if the vibrational movement is increased.</span>
The best answer would be "research reasons why species change over long periods of time"
if not i apologize but this is my best guess<span />
