Right answer is (c) Auxiliary

To elaborate: The tuyeres are responsible for the supply of air for combustion in the cupola. The tuyeres are always fitted in one or more number of rows. Auxiliary tuyeres being more efficient are fitted in the cupola to supply more air and increase melting efficiency.
