$H_2O$ is polar while $BeF_2$ is not. The reason for this is ...

• A
  $H_2O$ is angular while $BeF_2$ is linear.
• B
  The electronegativity of $F$ is higher than that of $O$.
• C
  $H_2O$ has hydrogen bonding while $BeF_2$ is an independent molecule.
• D
  $H_2O$ is linear while $BeF_2$ is angular.
