The order of increasing F-A-F bond angle, where 'a' represents central atom in each molecule is PF3 < OF2 < PF4⁺ that is option A is correct.

Bond Angle is defined as the angle that the central atom makes with the other atoms of the molecule. It is one of the properties of the covalent bond formation. Covalent bond is the bond that is formed by sharing of an electron pair between two atoms. Bond angle of any molecule depends on the number of electron pair that surrounds the central atom within the molecule. The bond angle may be determined by the structure of the molecule. The molecule PF3 has a trigonal planar structure and the bond angle value of 97.7°. The molecule OF2 has a bent structure and bond angle value of 103°. The molecule PF4⁺ has a tetrahedral structure and bond angle value of 109°. So, PF3 has least bond angle while PF4⁺ has most bond angle.
