I think the correct answer from the choices listed above is option A. For metamorphism to occur, the parent rock must be in solid form. Metamorphism is the alteration of the structure of a rock by factors like heat and temperature so it must be the material should be in solid form.
Greenhouse gasses have increased due to carbon emissions and the amount of fossil fuels that humans are burning and releasing into the atmosphere. These gasses are keeping earths heat trapped, causing global warming/ climate change.

Excited electrons are those which temporarily occupy a state higher than their ground state
The electron is excited if it is given extra energy, such as when a photon, or packet of light, absorbs it or if it collides with an atom.
Answer:
The most appropriate answer would be "There is a lack of genetic variation for selection to act upon.".
Evolution is a gradual and natural process by which the characters of a population changes over several generations with the help of natural selection.
Reduction of population size up to 100 to 160 decreases overall genetic diversity of the population due to which the efficiency of natural selection decreases.
Consequently, the population of panthers may no continue to evolve.
