The amount of NaF produced is doubled.
(d) is correct option.
Explanation:
Given that,
A 2 mole sample of F₂ reacts with excess NaOH according to the equation.
The balance equation is

If the reaction is repeated with excess NaOH but with 1 mole of F₂
The balance equation is

Hence, The amount of NaF produced is doubled.
(d) is correct option.
