Marks: +1, -0

Assertion (A): Fluorine forms only one oxoacid HOF.
Reason (R): Fluorine atom is highly electronegative.

Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.

Solution:

Both A and R are true but R is not the correct explanation of A.
Fluorine atom is highly electronegative. due to, absence of d-orbital, Fluorine does not form the oxoacids having higher oxidation state such as +3,+5,+7,.......... . That's why it only forms one oxoacid HOF.
