The Correct Option is A

Solution and Explanation

Step 1: Permutation Concept
A tripeptide is formed by linking three amino acids together.
Step 2: Calculation

Since there are 20 options for each of the three positions in the tripeptide chain, we use the formula $n^{x}$ where $n$ is the number of amino acids and $x$ is the length of the peptide.
Step 3: Result

Number of possible tripeptides $= 20 \times 20 \times 20 = 20^{3} = 8000$.
Final Answer: (a)
