The option that best completes the gap is "march past."
A march past is a parade or procession in which a group of people, often military personnel, march in formation past a reviewing stand or other designated location. This is a common activity during Independence Day celebrations, where students may participate by marching in a parade to honor their country's independence.
The other options, "match past" and "match pass," do not make grammatical sense and are not commonly used phrases in this context.
