Morphology

take + the + biscuit

The figurative sense 'to be the most extreme or outrageous' is not predictable from the literal meanings of 'take' and 'biscuit'; there is no transparent compositional link that would lead a learner to that idiomatic reading. This is a regional, conventionalized idiom (British, like US 'take the cake') and therefore a B1 learner who only knows the constituent words is unlikely to infer the intended meaning.

Etymology

Take the biscuit may come from an old tea-time image: someone grabbing the last biscuit in front of everyone and causing surprise or offence. So, to say someone takes the biscuit means they are 'the most extreme or surprising', often in a bad way.
