R be the relation in the set {1,2,3,4] given by R ={(1,2),(2,2),(1,1),(4,4),(1,3),(3,3),(3,2)}
it is seen that (a,a)∈ R for every a∈{1,2,3,4}
so,R is feflexive.
it is seen that (a,b) = (b,a) ∈ R
because, (1,2)∈ R but (2,1) ∉R
so, R is not symmetric.
it is seen that (a, b), (b, c) ∈ R ⇒ (a, c) ∈ R for all a, b, c ∈ {1, 2, 3, 4}.
so, R is transitive.
Hence, R is reflexive and transitive but not symmetric.

The relation R on the set {1, 2, 3, 4} is given by R = {(1, 2), (2, 2), (1, 1), (4, 4), (1, 3), (3,3), (3,2)}.
Let's analyze the properties of the relation R to determine its characteristics.
1. Reflexivity:
A relation is reflexive if every element in the set is related to itself. In other words, for every element a in the set, (a, a) must be in the relation.
In this case, we have (1, 1), (2, 2), (3, 3), and (4, 4) in the relation R. Therefore, R is reflexive.
2. Symmetry:
A relation is symmetric if whenever (a, b) is in the relation, then (b, a) is also in the relation.
In this case, we have (1, 2) in the relation R, but (2, 1) is not in the relation. Therefore, R is not symmetric.
3. Transitivity:
A relation is transitive if whenever (a, b) and (b, c) are in the relation, then (a, c) is also in the relation.
In this case, we have (1, 2) and (2, 2) in the relation R, but (1, 2) is not related to (2, 2). Therefore, R is not transitive.
Based on the analysis of the properties, we can conclude that R is reflexive and transitive, but not symmetric. Hence, the correct answer is option 'D' - R is reflexive and transitive but not symmetric.
