The table refers to the hydrogen halides. Which row is correct?

11.2.1 describe the relative reactivity of the elements as oxidising agents

11.2.2 describe the reactions of the elements with hydrogen and explain their relative reactivity in these reactions

11.2.3 describe the relative thermal stabilities of the hydrogen halides and explain these in terms of bond strengths

11.3.1 describe the relative reactivity of halide ions as reducing agents

11.3.2.1 aqueous silver ions followed by aqueous ammonia (the formation and formula of the $\left[\mathrm{Ag}\left(\mathrm{NH}_{3}\right)_{2}\right]^{+}$ complex is not required)

11.3.2.2 concentrated sulfuric acid, to include balanced chemical equations
