Among the items listed, the school bus pass would probably have inelastic demand for a student.
Inelastic demand refers to a situation where the quantity demanded of a good or service is relatively unresponsive to changes in price. For students, a school bus pass is often a necessity for getting to and from school, so they are less likely to reduce usage significantly even if the price increases.
In contrast, the other items (mouse pad, sneakers, ballpoint pen) could have more elastic demand, as students might find substitutes or forego purchasing them if prices rise.
