(D) cyclic tripeptide is formed by the condensation of $3$ amino acid units in a ring structure.Given $2$ types of amino acids,$A$ and $B$,each of the $3$ positions in the cyclic tripeptide can be occupied by either $A$ or $B$.The total number of possible combinations is $2^3 = 8$.However,in a cyclic structure,rotations are considered identical.The possible combinations are:$1$. $AAA$$2$. $BBB$$3$. $AAB$ (which is equivalent to $ABA$ and $BAA$ by rotation)$4$. $ABB$ (which is equivalent to $BBA$ and $BAB$ by rotation)Thus,there are $4$ distinct cyclic tripeptides possible: $AAA$,$BBB$,$AAB$,and $ABB$.
