Which of the following is/are TRUE in the experiment about SUDAN-1? 1. The preparation of phenyldiazonium ion was carried out at temperature below 5°C to prevent the formation of phenol. II. Two-pot synthesis was employed because the synthesis of precursors required different pH conditions. III. Excess HCI was added to the beaker containing ß-naphthoxide to neutralize the NaOH. IV. In ingrain dyeing, the dye is synthesized within the fabric. O O I, II II, III I, II, III I, II, IV
