Morphology
The meaning 'device used to block the drain of a sink' is directly and transparently derived from combining 'sink' (a basin) with 'plug' (an object that seals or blocks flow); the compound straightforwardly denotes a plug for a sink. This simple Noun+Noun composition follows common English patterns and has clear equivalents in many languages, so a B1 learner who knows both constituents would readily infer the meaning.
Etymology
Sink plug comes from the simple image of a small stopper you push into the sink hole to keep water from leaving. The word sink shows where it is and plug shows it 'plugs' the drain, so it means 'a device to block the drain and keep water in'.
