Algae and plants may look similar and belong to the same Eukarya domain, they don't belong to the same kingdom because they are simply different in many ways including in their behavior, structure and habitat. In totality, they differ in more ways than they are alike.
Plants are in the Kingdom Plantae, while Algae are in the Protista kingdom. Plants are multicellular, while most Algae are single-celled, although some can be multi-cellular.

I think it is C as plants take in Co2 and release oxygen which humans use to breathe.

By lesioning the medulla in rats, scientists were able to cause a cessation in breathing. By electrically stimulating the amygdala in rats, scientists were able to trigger aggressive behaviour.
The medulla or medulla oblongata is found in the brainstem and is the structure that regulates autonomic functions of breathing, heart rate and blood pressure. Lesioning is a surgical term which describes the process of injuring a specific part of the brain. Therefore, when the medulla is lesioned, it can no longer function properly and the autonomic process of breathing is interrupted.
The amygdala is comprised of two nuclei within the temporal lobes of the brain and is considered part of the limbic system. Its functions include the processing of memory, decision-making and emotional responses. It has been shown that by electrically stimulating the amygdala in animals, their aggressive behaviour is increased.
