(b) (ii) and (iii)

(c) (i) and (iii) 

(d) (iii) and (iv)

Answer 1

The correct option is (c) (i) and (iii)

• An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. 
• The formation of hydrogen fluoride is an example of a redox reaction. 
• We can break the reaction down to analyze the oxidation and reduction of reactants.
