is whats below a complete sentence or a fragment?\ngoing to hear optimus prime play guitar.\ncomplete…

Brief Explanations:

A complete sentence needs a subject and a predicate (a verb that shows the action or state). The phrase "Going to hear Optimus Prime play guitar" has a gerund phrase "Going..." but no clear subject performing the action, and it lacks a main verb in a finite form to make a complete thought. So it's a fragment.

Answer:

Fragment
