According to the way you defined the image, the right answer is C. Amino Acid.
The amino acids found in proteins all have the same basic structure: they are oriented around a central carbon atom, the α-carbon, on which the carboxyl group (-COOH) is articulated, the amino group (-NH2). ), a hydrogen atom (-H) and a lateral group (denoted -R). It is the nature of this lateral group (also called side chain) which differentiates the amino acids between them.
The central α-carbon is therefore asymmetrical in all cases except that of glycine (because glycine has a hydrogen instead of a side chain). This means that it is possible to have two different conformations of the same amino acid conformations that can not be interconverted without breaking and reassembling covalent bonds. These conformations L and D are designated. Although both can be synthesized in the same chemical reaction, only the L-form is used in the proteins.

Answer: d. Predators avoid prey that are in their prime in order to maintain a high reproductive rate in the prey population, and hence 'grow' prey for the future.
Explanation:
A predator can be define as an organism superior and strong enough to kill inferior and weaker organism. This organism kill other organism to obtain it as food. A prey is an organism which is weak and cannot defend itself from the attack of the superior organism.
d. is the correct option. This is because the predators do not bother about the age and strength of the prey. They attack over them whether the prey is weak , young, prime, or old and try to obtain it as food.
