Graph of angular velocity (ω) vs time (t) in seconds, showing four linear segments: increasing, constant, decreasing, and returning to zero.

The graph shows the angular velocity $ω$ as a function of time $t$ for an object that rotates about an axis. The time intervals labeled 1-4 divide the graph into four sections.

Which of the following correctly compares the angular displacement $∆ θ$ of the object during each time interval?

$∆ θ_{2} > ∆ θ_{1} = ∆ θ_{3} = ∆ θ_{4}$
$∆ θ_{2} > ∆ θ_{1} = ∆ θ_{3} > ∆ θ_{4}$
$∆ θ_{4} > ∆ θ_{3} > ∆ θ_{2} > ∆ θ_{1}$
$∆ θ_{1} > ∆ θ_{2} > ∆ θ_{3} > ∆ θ_{4}$
