The correct increasing bond angle among BF₃, PH₃ and CIF₃ follows the order

(A)        BF₃ < PF₃ < CIF₃

(B)        PF₃ < BF₃ < CIF₃

(C)        CIF₃ < PF₃ < BF₃

(D)        BF₃  PF₃  CIF₃

In BF₃, B is sp² hybridised

        \ Bond  = 120^o

        In PF₃, P is sp³ hybrodised, the molecule has pyramidal shape \ bond  is less than 109^o.28’ and greater than 100^o. In ClF₃, Cl is sp³d     hybridized, the molecule has a T-shape.

        \ the bond angle is close to 90^o.
