#2#.

Explanation:

There are two types of carbon-carbon covalent bonds:

  • #sigma# (sigma) bonds due to the head-on/axial overlapping of atomic orbitals
  • #pi# (pi) bonds as a result of the side-way/lateral overlapping of #p# orbitals

All carbon-carbon single bonds #"C"-"C"# are sigma #sigma# bonds; they contain no #pi# bonds.

Sigma bonds and pi bonds combine to form covalent bonds of orders higher than one. For example, each carbon-carbon double bond contains

  • one #sigma# sigma bond, and
  • one #pi# pi bond.

as seen in the diagram

The organic molecule shown in the question contains two carbon-carbon double bonds (shown in red). As a result, this molecule has two #pi# pi bonds.
