(i) Cytokinins promote cell division (found in higher concentration in fruits and seeds).
(ii) Abscisic acid inhibits growth.
(iii) Auxin — synthesised at the shoot tip, it detects light and causes the plant to bend towards light.
(iv) Abscisic acid causes wilting of leaves.

All four answers come from one paragraph in Section 6.2.2. Examiners expect the correct hormone name for each process — misspelling "abscisic" or "cytokinin" can cost marks. Note that abscisic acid appears in both (ii) and (iv) — wilting of leaves is given as a specific effect of the same hormone that inhibits growth, so both sub-parts share the same answer.
