Answer: The correct option is,

A. <

Step-by-step explanation:

Given,

[tex]8=x+y-----(1)[/tex]

Also,

[tex]y > 0[/tex]

Adding x on both sides ( additive property of inequality )

[tex]x+y>x+0[/tex]

[tex]x+y>x[/tex]

From equation (1),

[tex]8>x[/tex]

Hence, x is less than 8,

We use < sign for less than,

⇒ x is '<' 8

Option A is correct.
