The Short Answer

They're the simplest method of providing a chord sequence, a harmonic backup, and a rhythm, all while being easy to learn, store, transport, and amplify. The guitar and piano are the most common instruments capable of playing full chords – other lead instruments (think saxophone, trumpet, violin, etc) are only able to play a single note, requiring other band members to back them up to flesh out chords. Of the two, guitar and piano, guitar is a bit easier to learn and to play simple chord structures, and it's much, much easier to travel with and set up. The bass is popular for the exact same reasons as the guitar, except instead of a chord structure, it gives you a harmony, countermelody, and bass support. The drumset is simply the most convenient way for one person to provide any percussion needed to keep a rhythm in various styles. They're completely modular, meaning you can modify them with anything – tambourines, gongs, xylophones, whatever.
