The correct answer is: marsupials.
Marsupials are actually defined by their ability to hold the young in the pouches, where they can be well protected. Some examples are Kangaroos and Koalas.
Other answers are wrong: for example, gymnosperms are plants, not animals.

<h2>D) option is correct </h2>
Explanation:
During citric acid cycle, Acetyl Coenzyme A is completely oxidized in form of CO2 and produce NADH, FADH2 and GTP (ATP)
Succinate is converted to fumarate with the help of succinate dehydrogenase and FADH2 is produced during this step
In the given conditions, if the amount of succinate is increased in comparison to malonic acid then it reduces the effect of malonic acid, therefore malonic acid will not be able to inhibit the conversion of succinate to fumarate and hence succinate will be the substrate and fumarate, the product in the reaction
