When does an inequality have a solid line

The question is pretty straightforward and the answer is (b) which means that when the symbol has or equal to.

This implies that, the symbol could be:

> or = i.e.
`\ge`

and it could also be:

< or = i.e.
`\le`

`x + 1 \ge 2` and
`y- 5\le 10`

The above expressions will have a solid line
