Given a single triglyceride which contains three identical and fully saturated fatty acid residues, which of the following terms accurately describe(s) it?
A) chiral
B) optically active
C) meso
D) optically inactive
E) both A and B
Triglyceride
A triglyceride is a type of fat molecule made up of three fatty acids linked to a glycerol backbone, commonly found in the human body and in foods.
Optically Inactive
Describes compounds that do not rotate the plane of polarized light, usually because they are achiral or have a symmetrical arrangement of atoms.

Final Answer :
D
Explanation :
A triglyceride with three identical and fully saturated fatty acid residues is symmetrical, meaning it has a plane of symmetry through its molecule. Therefore, it is optically inactive (D). It is also not chiral (A) or optically active (B) because it lacks a stereocenter. It is not meso (C) because meso compounds have stereocenters and a plane of symmetry, but this triglyceride does not have any stereocenters.
