Answer :
To answer this question we have to understand what each of the signs represent.
The first one
[tex]<[/tex]Means that a number to the right is lower than the one from the right. In this case
[tex]3<5[/tex]Since 3 is lower than 5 this stament is true.
The second sign
[tex]\leq[/tex]Means that the number on the right is lower OR equal to the one on the right. In this case
[tex]3\leq5[/tex]Since 3 is lower than 5 this statment is true.
For the third stament we have the same sign than the second statement
In this case
[tex]7\leq7[/tex]Since 7 is equal to 7, this statement is also true.
Finally , the sign
[tex]\ne[/tex]Means that the number on the right is not equal to the one on the right
In this statement
[tex]7\ne7[/tex]This says that 7 is not equal to 7, which is not true.
So the answer to the problem is d.
