If $\tan y$ is positive and $\sin y$ is negative, in which quadrant would $y$ lie?

Worked solution (try it first)

Sine is negative in the third and fourth quadrants.
Tangent is positive in the first and third quadrants.
Only the third quadrant is on both lists, so the answer is the third only, option C.
