Which of the following are reflexive relations on set `A={1,2,3}`.
`R_(1)={(1,1),(2,2),(3,3),(1,3),(2,1)}'.
'R_(2)={(1,1),(3,3),(2,1), (3,2)}`

Explanation

To determine whether the given relations \( R_1 \) and \( R_2 \) are reflexive on the set \( A = \{1, 2, 3\} \), we need to check if each relation contains all the pairs \( (x, x) \) for every element \( x \) in the set \( A \).

### Step-by-Step Solution:

1. **Identify the Identity Relation**:
The identity relation on the set \( A \) is defined as:
\[
I = \{(1, 1), (2, 2), (3, 3)\}
