To answer this question we have to understand what each of the signs represent.
The first one

Means that a number to the right is lower than the one from the right. In this case

Since 3 is lower than 5 this stament is true.
The second sign

Means that the number on the right is lower OR equal to the one on the right. In this case

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

Since 7 is equal to 7, this statement is also true.
Finally , the sign

Means that the number on the right is not equal to the one on the right
In this statement

This says that 7 is not equal to 7, which is not true.
So the answer to the problem is d.
