Answer:
Option: d is the correct answer.
Step-by-step explanation:
We know that a even function is a function that satisfy the symmetry relations.
The graph of a even function is symmetric about the y-axis.
i.e. when the graph f such a function is reflected about the y-axis then it remains unchanged.
From the given graphs we see that the graph of an even function is represented by: Graph d.
( Since when graph d is reflected across the y-axis then the graph remains unchanged)
