Teichoic acid is present in the cell wall of bacteria.

Here’s a detailed explanation:

Teichoic acids are polymers of alcohol and phosphate found in the cell wall of Gram-positive bacteria. They are covalently linked to peptidoglycan, a component of the bacterial cell wall, and contribute to the structural integrity of the cell wall.
Gram-negative bacteria do not contain teichoic acids in their cell walls. Instead, they have an outer membrane.
Teichoic acids play a role in cell wall maintenance, ion regulation, and can also act as receptors for certain bacteriophages.
Therefore, the correct answer is: a. Cell wall.
