'Besides' means 'in addition to' or 'apart from', which fits the context of asking what other sport is played in addition to hockey. 'Beside' means 'next to' (physical location), which doesn't fit. 'Instead' would require 'instead of'. 'Expect' is unrelated. Therefore, 'besides' is the correct preposition.
