The answer to this question is quadrant III. Since
sinθ = y/r and tanθ = y/x, we have, in quadrant III, x, y negative.

sinθ < 0 (r always positive) but tanθ > 0 (negative divided by negative is positive).

Answer:

Option c. is correct.

Step-by-step explanation:

if sin\theta < 0 means values of sin\theta will be negative.

For tan\theta =\frac{sin\theta }{cos\theta } > 0 means  positive value of tan\theta

values of sin\theta and cos\theta  both should be either > 0 or < 0 for the poitive values of tan\theta. If any one, sine or cosine is negative then tan\theta will be < 0

We know that for the condition tan\theta > 0 and sin\theta < 0 value of cos\theta should be negative.

Therefore, \theta should lie in 3rd quadrant where sin\theta and cos\theta both are negative.

Option C. 3rd option is correct.
