Hello @shathriyan94434
Not sure if it’s possible to achieve this at query level. You could try a different approach. Use templating to dinamically change the severity level of the label (so if a condition is met, the severity of the label will change, and so a notification will be sent to the matching contact point.
Here is another post for reference
You would add a reduce expression (last,strict), and a math expression. In the math expression, you could try something like:
$B >= 80 || $B >= 50
GL and Let us know if it helped.
