Option 1: While both statements are individually true, the reason does not correctly explain the assertion. The essential amino acids which cannot be synthesized by our body must be included in our diet, but Glycine, Serine, and Tyrosine are non-essential amino acids which the human body can synthesize on its own.

Option 2: The statements are both individually true, but the reason is not a correct explanation of the assertion since Glycine, Serine, and Tyrosine are non-essential amino acids.

Option 3: The assertion is false as Glycine, Serine and Tyrosin are non-essential amino acids, meaning they can be synthesized by the human body. The reason is true, stating that essential amino acids cannot be synthesized in the human body.

Option 4: This is the correct answer. The assertion is false because Glycine, Serine and Tyrosine are non-essential amino acids. The reason is true because essential amino acids cannot be synthesized in the human body, and should be included in our diet.
