Answer:

Option D

$180\°< \theta < 270\°$

Explanation:

we know that

If
$sin(\theta) <0$

then ------> the angle could be in the III or IV quadrant

If
$tan(\theta) >0$

then -----> the angle could be in the I or III quadrant

so

The angle belong to the III quadrant

therefore

$180\°< \theta < 270\°$
