• C. The living systems in animals can synthesize only non-essential amino acids.
• D. The living systems in plants can synthesize non-essential amino acids.

Answer 1

The correct option is B

The living systems in animals can synthesize only essential amino acids.

Explanation of correct option:

Option (B):

• Amino acids are the organic compounds that combine to form proteins, so they are also known as the building components of proteins.
• Plants can synthesize all amino acids but animals can synthesize only non-essential amino acids.
• Thus, the given statement “the living systems in animals can synthesize only essential amino acids” is not correct.

Explanation of incorrect options:

Option (A):

• The living systems in plants can synthesize essential amino acids. This statement is correct.

Option (C):

• The living systems in animals can synthesize only non-essential amino acids. This statement is correct.

Option (D):

• The living systems in plants can synthesize non-essential amino acids. This statement is correct.

Hence, option (B) is the correct answer.
