A thin uniform rod, pivoted at \( \mathrm{O} \), is rotating in the horizontal plane with constant angular speed \( \omega \), as shown in the figure. At time \( \mathrm{t}=0 \), a small insect starts from \( \mathrm{O} \) and moves with constant speed \( \mathrm{v} \) with respect to the rod towards the other end. If reaches the end of the rod at \( \mathrm{t}=\mathrm{T} \) and stops. The angular speed of the system remains \( \omega \) throughout. The magnitude of the torque \( (|\vec{\tau}|) \) on the system about \( O \), as a function of time is best represented by which plot?
