They have to offer a rebooking option. There isn't a direct right to use other airlines but if BA isn't operating the route at all then it's difficult to avoid that. Right to care costs are preserved if you're held up overnight but BA won't normally state that before travel. Recording your rejection of the BA option(s) is worth doing, depending on what the outcome becomes.
