Option B, “Industries relating to production of non-cellulosic synthetic fibres,” does not fall under the control of the Department of Fertilizers.
The Department of Fertilizers deals with the planning, promotion, production, import, and distribution of fertilizers, as well as the administrative responsibility for public sector undertakings and cooperative societies engaged in fertilizer production and marketing (like IFFCO). Industries relating to the production of non-cellulosic synthetic fibres are subjects allocated to the Department of Chemicals and Petrochemicals.
Similar to the previous question, the Ministry of Chemicals and Fertilizers is divided into specific departments. Fertilizers are distinct from chemicals and petrochemicals like synthetic fibres, which fall under the purview of the Department of Chemicals and Petrochemicals.
