An isolated object at rest on a horizontal, frictionless surface explodes into three distinct fragments that move along the surface. In a coordinate system where each grid unit represents an equal unit of momentum, Fragment 1 moves with momentum \(\vec{p}_1\) along the positive \(x\)-axis with a magnitude of 4 units, and Fragment 2 moves with momentum \(\vec{p}_2\) directed 2 units left and 3 units upward. Which of the following vector diagrams could correctly represent the momentum vectors \(\vec{p}_1\), \(\vec{p}_2\), and \(\vec{p}_3\) of the three fragments immediately after the explosion?
