Letters C, D, and E are the correct answer.

Explanation:

Global warming refers to a rise in the Earth's average temperature. Since the temperature raises little by little, this effect can be seen and studied in the long-term.

Genetic changes also happen through generations; even though some of their effects can be seen in short-term, they would only be completely understood or analyzed in the long-term.

Large asteroid impact might be a little confusing. In spite of the immediate effects (like a crater or the end of the species) the complete effects would develop with time, and they could take even millions of years to be totally displayed.
