1. The electronegativity difference between the atoms of the most polar bond is the highest.
A. C-O:
The electronegativity value of C is 2.5.
The electronegativity value of O is 3.5.
Difference = 3.5-2.5 = 1
B. Si-F:
The electronegative value of Si is 1.8.
The electronegativity value of F is 4
Difference = 4-1.8 = 2.2
C. Cl-F:
The electronegativity value of Cl is 3.
The electronegativity value of F is 4.
Difference = 1.
D. C-F:
Differene = 4-2.5 = 1.5
E. C-I
Difference = 2.5-2.5 = 0
Therefore, option B. Si-F is most polar bond.
