not really a doubt but is it advisable to just put a=1 (in exam not whilst practicing ofc ) and solve the integral (ik 0<a<1) . it comes out to be something/0 form which is only achievable with option C. this makes the ques much much more easier

putting a=1 gives us 2(1-cos(theta))=4(sin^2(theta/2)) which is csc^2 ka integral with 0 as a bound which tends to infinity
Ye this works. But in some cases it may be misleading.
Like ln(sin(x))
You might think it tends to -infinity near 0, but its definite integral exists. (from 0 to pi/2)
So just try to look at it carefully

Gahh I've solved it somewhere but it was soo long ago it will be hard to find that thread. :/
