Potassium bromate is carcinogenic and not neurotoxin. So, the fourth statement is not correct. On 21st June, 2016, the government banned the use of potassium bromate as a food additive following a Centre for Science and Environment (CSE) study that found its presence in bread caused cancer. FSSAI (Food Safety Standards Authority of India) had banned potassium bromate and had recommended to the Health Ministry to remove it from the list of permissible food additives. Potassium bromate, or simply called bromate, is an oxidiser used to strengthen the dough and enhance its elasticity. This helps bake uniform and whitened bread.
