In graphite, electrons are

In graphite, electrons are
  1. Localised on every third C-atom
  2. Present in anti-bonding orbital
  3. Localised on each C-atom
  4. Spread out between the structure

Solution

In graphite, each carbon is $\mathrm{sp}^{2}$-hybridized and the single occupied unhybridized porbitals of C-atoms overlap side wise to give $\pi$-electron cloud which is delocalized and thus the electrons are spread out between the structure.
