correct answer is

Answer 2

Answer:

$\frac{\pi }{2}$ (Option b)

Step-by-step explanation:

Given sinθ = cosecθ

=> sinθ = 1/sinθ

=> sinθ ^ 2 = 1 = (sin$\frac{\pi }{2}$) ^2

=> sinθ ^ 2 = (sin$\frac{\pi }{2}$) ^2

So θ = n$\pi$ ± $\frac{\pi }{2}$

when n= 0,

then  θ =  $\frac{\pi }{2}$

So option b is correct.
