The correct increasing order for bond angles among $\mathrm{BF}_3, \mathrm{PF}_3$ and $\mathrm{C} / \mathrm{F}_3$ is :
  • A
     $\mathrm{PF}_3<\mathrm{BF}_3<\mathrm{C} \ell \mathrm{F}_3$
  • B
     $\mathrm{BF}_3<\mathrm{PF}_3<\mathrm{C} / \mathrm{F}_3$
  • ✓
    $\mathrm{C} / \mathrm{F}_3<\mathrm{PF}_3<\mathrm{BF}_3$
  • D
     $\mathrm{BF}_3=\mathrm{PF}_3<\mathrm{C} \ell \mathrm{F}_3$
